Don't have an apple ][ to begin with so can't use that to test NTSC anyways... But indeed the PS2 I use might be too clean but I doubt my 32X is much rougher, and both are currently the best indicator to test if any of my screens do NTSC in the first place.

That doesn't mean much. Try an Apple II - if that shows color over composite with your TV, then an XT should as well. Problem with the XT and other computer systems from that time is that the NTSC signal is rather rough and not within specs. Unlike your consoles, which will most likely output a perfect NTSC signal.
It can also be a cable-related issue. Some devices do output a NTSC signal, but via a non-standard connector (or a standard connector that is wired differently), and then you need a custom cable.
If your TV has a SCART connector, you may also want to try a composite-to-SCART convertor box, as some modern TVs will accept more diverse signals over SCART than over composite. On mine SCART accepts many more resolutions than composite in.
(as an aside, if your consoles can output RGB, and your TVs take SCART, get RGB SCART cables for them. You'll enjoy the much better picture quality...)
I highly doubt it's the cable as it's a standard RCA audio cable I stole from my sound system. And it's just composite and ground lines, flipping that you don't get any signal I believe.
As for RGB, way ahead of you. Nearly all my consoles are RGB or RGB modded (unless they need some added board like the Famicom to get RGB), even got a early French model N64 to get "official" RGB out of a N64. (those models had unpopulated RGB circuitry)
That said, composite over SCART does work better with my PS2 that I use to test PAL/NTSC. As the composite in doesn't do PAL (for some reason, probably me fiddling to much with it a few years back no clue how I did that though) and the composite over SCART does both PAL and NTSC.

Composite colour does not work in the 80-column textmode that is used on bootup. It only works with 40-column text and graphics modes.
I use California games, which I believe should do proper composite.
