My take is 1440p for 26">= screens @ 120-144Hz for the premium gaming experience. I play on a 24.5" @ 144Hz 1080p, I picked a smaller sized screen because I built an sffpc setup for ease of transport. But yeah 4k is a meme, 1080p is ok for screen with a size below 26".
Then there's the screen panel type (IPS, TN, VA debate EXCLUDING CRT), but that's another can of worm...
Beside that I'd like to shill Keychron keyboards, they're very good build quality if you're looking for a nice mechanical keyboard. They're very sturdy and you can buy spare keys/switches to replace in case one stops working properly.
Keychron design and produces custom and wireless Mechanical Keyboard for Mac, Windows, iPhone and Android.

I'm using the Keychron K3 (low profile) since 2020 and I will personally attest that it is an excellent keyboard, very light and easy to carry around, can be wireless or USB-C wired. You can very easily replace sticky/used/broken keys if you buy some spare parts. I had a couple of accidental fluid spillage that ruined some keys, took 10 minutes to replace them and I resumed what I was doing as if nothing happened.
Compact, light, sturdy, backlit, easy maintenance, replaceable keys/switches/cable, typing feedback is nice, no frame deformation, no software and no gimmick features. I give it a 8.5/10, it's not a 10 because the keys are ABS, if it was PBT it would be a 9.5.
