I found a shareware program called "Hogs" or "Memory Hogs" by Kamyan Software which doesn't show addresses, but shows total memory usage for each module, sorted from highest to lowest. The list of modules seems to include drivers, and also down the bottom it has fonts which take up 0.2KB each. If you don't check "Show DLLs", it won't show significant parts of Windows itself like GDI and USER and less significant parts like the fonts, just programs.
Here I gave my emulated machine 4MB of RAM. The DOS MEM command showed about 500KB of conventional memory and all 3MB of extended memory available before I started Windows, and when I added the sizes of all the modules shown by Hogs to the free memory it came out to close to 3.5MB, so I think it can see everything, or just about everything.
As I said, it's shareware. It has a registration fee of $15 and I would feel bad using it without paying since it's not hard to track down the author, but based on this post where he released the full version of a shareware game he wrote back then, it looks like he'd probably be happy to make it freeware if anyone asked: https://www.pixarra.com/pendulous.html I might ask if nobody beats me to it and I end up wanting to use it for something.
Next I want to check out McAfee's Proview for Windows. I used it back when it was new, but only briefly, mostly using the DOS version. I'm not sure if it provides this kind of information about memory usage, but the DOS one did regarding DOS memory.

For anyone who is interested, I found it by browsing random shovelware CD indexes on cd.textfiles.com. I noticed that most memory-related programs seem to describe themselves as just showing the amount of memory free and used, resource usage, etc., and this was the first one whose description (in http://cd.textfiles.com/wthreepack/wthreepack … CDM/TEXT/MEMORY - yes that's a different CD, I searched the site for a newer version after reading that description) said it actually listed programs. I stopped looking after I found this one so there might be other/better ones out there.
