As an owner of roughly 15 CRT monitors, here's my two cent's worth. 😉
First, consider if you actually even need a CRT. As much as I love using mine and used to avidly recommend CRTs back in the days when you could still get them for free (10+ years ago), I can now see that they are indeed not for everyone. And here are the reasons why:
1) Probably the most important thing that no one seems to mention is that CRTs are a very poor choice for rooms/areas with lots of light (be it natural or artificial light.) This comes from the fact that the glass in CRTs "traps" light from external sources and then re-reflects it back. The result is usually washed-out looking picture/colors and a screen that is very hard to see. Think of the early glossy LCD screens and then make it about 2-3x worse.
So with that said, only consider getting a CRT if you have a dark room to use it in *OR* only if you are okay with using it in the late afternoons / evenings / early mornings before the break of dawn. I do the latter myself (only use my CRTs in the afternoon evening with no lights in the room) and it's a much more satisfying experience. During the day, they are just a pain to use, so I switch to my LCD(s).
2) If #1 is not an issue, then here's another consideration for you: most CRTs are now 20+ years old. At this age, quite a few are getting due for a recap. I opened up a 15" HP built in the early 2001's by a no-so-widely-known Chinese monitor manufacturer, Chunghwa. It was filled with cheap caps, most of which were starting to fail or go out-of-spec. The monitor was still working, but the picture left a lot to be desired. Recapping it fixed some of that (but unfortunately, there was also heavy burn-in on the screen from the monitor being used as a... well... constant app monitor of some sort, likely in an IT environment.) This is not the only example. A lot of my Samsung CRTs are now also starting to "get tired" from all of those years of use and probably will be due for a recap in a few more years, if not sooner.
So in short, it's getting harder and harder nowadays to find a CRT that doesn't or won't need any kind of maintenance soon. Getting a NOS (new old stock) monitor also might not necessarily avert any of that, since electrolytic caps just sitting without use still ages them (in some cases worse than if they are used.) On the other hand, you have to be careful with used monitors too, since they could have heavy burn-in or possibly too many power-on hours and parts (caps) getting tired inside. And lastly, even if the monitor is perfectly functional, beware that its plastics might also be on the virge of collapse. Two years ago when I was moving and packing my CRTs, I put a huge hole through the side of the case on one of my 19" CRTs. For many years, I had noticed that this monitor was starting to develop cracks around the screen bezzle, thinking it was just something cosmetic. Turns out, the ABS plastic on the case had become very brittle. Even though I picked up and boxed the CRT properly, just exerting the smallest of tension on the side wall of the case made the plastic break. So that's another thing to beware about some CRTs - their cases may be getting very brittle.
All of these are reasons I always recommend to get monitors locally so that you can see in what condition they are in.
TLDR: if you can have a CRT monitor demonstrated in front of you before you buy it, that's the best way to proceed. Otherwise, getting a monitor that was just briefly tested to power on or without seeing how the picture looks on it in use (e.g. in Windows or games) could mask any issues the monitor might have. And if you get something like that, there's a good chance it will need work done to it soon. For people with electronics repair experience, these are usually relatively easy to refurbish (except for a worn tube.) But for non-technical people, they'll be stuck with either a non-working or poorly working monitor. So that's another reason why I say CRTs are not for everyone.

Which screen size would you recommend for gaming?
For DOS gaming, 15" to 17" max.
For late 90's and early 2000's games, 17" will do.
For late 2000's and early 2010's (if you go that far), 17" could still do OK, but a 19" will likely be better.
For (relatively) modern gaming (i.e. eSports like Rocket League, CS2, GTAV, Fortnite, etc.), probably a 19 or 21" to handle higher resolutions and refresh rates better... though I can't say I recommend CRTs for modern gaming too much, since many games' POV is usually more optimized for widescreen.
My personal opinion is that a late (late 90's to early 2000's) 17" is probably the best compromise between all of the sizes. It should be able to handle decent refresh rates (75+ Hz) at 1024x768 and sometimes even at the "higher" resolutions (i.e. 1152x864 and 1280x960.) Same goes for 19" CRTs. But if you play more games from the 90's, especially at 800x600 and below, then a 19" would be a bit of waste. In fact, if all you want to do is DOS and late 90's gaming, a late 15" would likely meet all your needs.

And which crt models would you guys consider worth checking out?
Anything that you can see working. 😀
Well, Dell, HP, SGI, and IBM from the late 90's and early 2000's is usually a pretty safe bet. These companies re-branded CRTs from known good tube manufacturers like Sony, Samsung, Hitachi, Mitsubishi, LG, Phillips, and NEC. Of course, any monitors from these manufacturers directly (i.e. Sony, Samsung, and etc.) is also a pretty safe bet. Sony and Hitachi in particular have superb built quality, normally due to using Japanese electrolytic capacitors, so they tend to last longer at least in that area.
That said, I do have some models of CRTs that you should AVOID:
Sony GDM-FW900 - yes, the legendary 24" widescreen CRT that everyone seems to praise (mostly people who haven't owned one or for too long) and think these are great. Reality check: they are not. They have many issues. Probably the worst one is that the picture tube in these is actually very prone to going defective and loosing vacuum over time. Happens frequently enough that I've seen just about as many out there with failed tubes as with working ones (and I have one failed myself.) If that's not the case, their screen AR coating is susceptible to developing "cataracts" - spots where the AR coating is starting to flake off or lift up, causing a slightly hue-y image. Then there's the "over-brightness" problems on these, stemming from an MCU-controlled G2 rail that keeps cranking itself up and up. The fix for that one is to connect the monitor to a special serial-to-TTL jig interface and fix the issue with WinDAS software (the Sony software that can tweak options within the monitor's firmware.) And to top it all off, there is a self-biasing circuit on the RGB cut-off amp that makes the monitor colors really washed out at startup. Removing/disabling this circuit and then tweaking/fixing the G2 overbrightness issue is the correct way to go about these, which even most CRT service experts don't know about. So not exactly a friendly monitor to use as-is.
That said, all of the above issue extend to many of the late Sony-built 21" CRT monitors (except the issue with the tube loosing vacuum.) Thus, contrary to what was said here about Sony Trinitron monitors being "the best", I would say to generally avoid post-2000's 21" Sony Trinitron or any other brand that uses these (e.g. Dell P1110 and IBM P260, to name a few)... basically anything based on the CPD-G500 chassis. I don't remember if the post 2000's 17" and 19" Trinitrons had these issues though. In any case, my observation has been that Trinitron CRTs with the completely flat screens (post 2000's) are not that great compared to their older vertically-flat siblings from the late 90's. I like the picture quality on my D1626HS a lot more than on my E540 (both are 21" CRTs, but former is from '98 or '99 and latter is from 02 or 03, IIRC.) The E540 is not from the CPD-G500 chassis, IIRC, but it also has the over-brightness / washed out colors at startup issue. The D1626HS does not and looks good. That said, both have mediocre contrast... and no way to fix it (I've tried all kinds of adjustments and settings, but got to the conclusion that the RGB amp circuit design is just the limit here on both.)
On that note, here is another observation of mine that might be worthwhile to consider:
Bigger CRT screens tend to have worse contrast.
What I mean by this is that the range of brightness between full black and full white levels is much smaller on the larger CRTs (particularly the 21" screens) than on the smaller CRT tubes. Let me give an example here: on my D1626HT, if I turn down the brightness so that full black starts to become truly black (i.e. cannot see anything on the screen even in a completely dark room), then full white becomes rather dull and not very bright. And if I crank the brightness up to make full white nice and bright, then the full black level looks kind washed out. In other words, I can never have both - something that is also an issue on my E540, GDM-FW900, and many other 21" CRTs I have used (even non-Sony brands too... though it's probably the worst on late Sony CRTs for whatever reason.) This is not so much the case if I go down in size to 19" CRTs, both for Sony and other brands as well. Most of my 19" CRTs can have near perfect black levels while maintaining really good and bright white levels - i.e. a picture with really good contrast. And if I go further down to 17", I can have pitch-black black levels and retina-burning white levels at the same time, further boosting the contrast.
With that said, if you want to experience more cinematic gaming, I'd say don't go further than a 19". Better yet, 17" screens are even more likely to give better contrast, so that's another reason to consider these (in addition to being more abundant, easier to find, and usually cheaper too.)
The only weaker side of 17" CRTs is that they don't usually look good/sharp past 1152x864. For some, even 1024x768 can be a stretch (e.g. NEC "Chromaclear" tubes, which is a hybrid between shadow mask and apperture grille, with pros and cons from both.) Though I do have one that looks acceptably sharp at 1280x960 - a 17" Dell M782 (Samsung rebrand). I prefer to use it at 1152x864 @ 75 Hz, though. Looks OK at that resolution even with some modern-ish games (GTA:V). Actually more than OK. And Half-Life 2 and most Source -based games are perfect.
On my 19" CRTs, I usually do 1280x960 (@ 75 or 85 Hz) at the most. Some of them are capable of 1600x1200, but don't really look that sharp. If I play with custom resolutions, 1440x1050 is about as high as some of my best shadow mask tubes will look good. All in all, though, I'm not a fan of pushing the highest resolution on a CRT. Better off using a lower resolution and a higher refresh rate than the other way around... though I don't usually go past 85 Hz either.

Tbh, unless you live in some paradise with huge diversity of monitors available in good state for an acceptable price, it's not that useful to choose the 'best' first and the try to find it. Much better to look at what is available and choose the best match
Agreed.
Just see what you can get locally, get it, try it, and if you don't like it, sell it off and try something else.
If you're OK with doing or have done electronics repairs, don't be afraid to look into any broken / non-working monitors either.
The last "decent" CRT I picked up was a 19" Illaiyama for $5 locally due to being non-functional. Ended up needing a new HOT and a recap.... mostly just repetitive work and not something that required a lot of proprietary tools or extensive electronics knowledge. Board was a breeze to work on even with a cheapo soldering iron.
