Ultrawide monitor with KVM recomendation for Air M2?

I'm looking for recommendations on ultrawide monitors (preferably that have a built in KVM) that other users using and know work well with a Macbook Air M1 or M2.

Longer story:

I recently picked up an Macbook Air M2. I'm loving it with one exception. Apparently my beloved Dell u3419w monitor has some issues with UBC (doesn't like the macbook shutting down) and worst of all it has fallen prey to Apple ditching anti-aliasing / not supporting lower DPI monitors. The result is fuzzy / blurry fonts and so on. I've tried solutions like Better Display (https://github.com/waydabber/BetterDisplay) but really not seeing a difference outside blowing up the text so large that the monitor is unusable.

I'm a developer so I love having enough space for 3 screens on one monitor.

Reviews on the internet are kinda wonky / hard to know if anyone really tested it on a mac so I was wondering if anyone in the community here have some ultrawide monitors (preferably with a KVM (to switch back to my old desktop PC from time to time)) that they like working with their Macbook Air.

Thanks for any recommendations.
