the HD 7000 series (apart from a few rebranded TeraScale cards) is still supported and works pretty well on windows 10 indeed, I'm using an HD 7850 right now and it's a pretty smooth experience,
I think some HD 7700s had dual dual-link DVIs and these cards are not power hungry or anything, also much faster than a 710 and very cheap on the used market?
the HD 5000-6000 series had official driver releases for Windows 10, and it works OK, it's stuck in 2015 and WDDM 1.3 but I've used an HD 5850 for a while after that and it was mostly fine,
HD 4000 series gets the windows update driver which works OK on 1909 for me, it's WDDM 1.1 and lacks the Catalyst Control Center, but for basic performance the card performs as expected, I even used it for some gaming like this, the main issue for me was the lack of CCC, because when used with HDMI the card sets a default overscan which you can't adjust! (not a problem if using DVI or VGA) I solved the problem by using the catalyst 13.1 from AMD's website and adjusting the overscan in there, after that I even updated to the default driver again and it kept the adjustment,
other than that, yeah these cards are very old, the HD 4000 is OGL 3.3 (and not good at that, I had some OGL 3.3 software fail to run, but that isn't win 10 specific), also the video decoder is very outdated and doesn't play well with all software, and even if it does it the hardware can't handle 1080P60 for example (so it's better to let the CPU do the work)
I think the video decoder on my 8400GS G98 performs a little better even compared to the HD 5850.
