Given his specific needs, I would look at the
Dell UltraSharp U3223QE. That monitor will have everything he's looking for and then some...
100%!
I just got 2 of the 31.5" ones on Black Friday and love them. They're very clear, even being 4k @ 31.5". I would highly recommend them, at least for workflows if you don't need more than 60Hz.
I don't play games or need more than 60Hz, but for my needs these are excellent monitors. Great color, nice blacks and plenty of brightness. They have some HDR support, but I haven't really explored that yet so I can't comment on that part.
But I did spend months looking and deciding tirelessly for a monitor and finally pulled the trigger on 1 of these. After using it for 3 days, I ordered the second one. I now have them next to each other and could not be happier.
Whichever way you go, hope you find what you're looking for and that fits your needs.

I forgot to mention:
- These do not have built in speakers, but I'd just recommend using some good external ones, there are even some <$30 pairs that sound pretty good. I actually bought a set of those Pebble v3 speakers from Creative for a family member at Christmas for some simple stereo sound. They actually sound pretty good for the price, which I got on sale but aren't too expensive (https://www.amazon.com/Creative-Minimalistic*************Bluetooth-Converter/dp/B08F57GSJ7). I use a 5.1 system for myself, and can't really compare those Pebble speakers to other good products out there, but just for a real world product that I've actually heard, they sound pretty good and fit on a desk nicely.
- Text clarity is very good on these, again - even with them being so big and
only 4k. I am very happy with the clarity and do mostly programming type work all day long.
- These have multiple inputs, HDMI and DP if needed. Or you can run using USB-C (not Thunderbolt, but you you could use a TB cable if you wanted to, although it wouldn't provide any benefit).
These are my first 4k monitors, so I can't really compare. But I do also have an iMac with a 5K display, and while it's definitely nice and sharp, these are definitely still extremely sharp.
