Gaming Monitor for boyfriend Christmas present

Hello everyone. I hope this is allowed here, as I'm not too sure where else I should be posting this. My boyfriend and I are looking to move into our first property within a few months, and my boyfriend has always said he'd love a little office where he can game online with his friends. So, for Christmas this year, I thought it would be nice of me to get him a gaming monitor

He plays on an Xbox series X and plays on the new COD (both gameplay and online), Red Dead Redemption, and FIFA (both gameplay and online) mainly. Please could someone advise which of the following monitors would be best for his style of gameplay?

I've tried doing my own research and these all seem really similar, but I haven't a clue about gaming at all really! Sorry if this isn't the right place to post this question!

EDIT: My max budget is £150 (approx $190). He'll mostly be using it, but I may occasionally use it to work from home, or play on my own game (The Sims 4)
