What 4K monitor/TV for a PS5

(not so) Mini B&B has had a PS5 since they came out. It's currently hooked up to a decent quality Samsung hotel 2K/1080P TV that I was given a few years ago.

I am thinking about getting a 4K  TV/Monitor for him for Christmas, but know next to nothing about them.

This one gets a good review online and is (very) expensive, but not a mad price. Would it be a good choice? If not, what is better without breaking the bank (cheaper than this would be good!)

Is a curved monitor 'better'?

PS - We tried a twin screen setup for a while, but the sights on the FPS games he plays where right on the 'join' so that was rejected.

PS II - I think the existing one is 32inch, but will sneak in a look when he goes to work
