Help with 4 monitor setup for work/play/music

Some context:

Pic is my current temporary setup. I’m going to be getting 1 or 2 desks soon as a more permanent solution.

The monitors are a curved 34” ultrawide, and 2 27” FHD monitors.

I’ve just acquired for next to nothing an LG 32” flat monitor too.

I work from home part of the week and use a windows laptop.

I have a gaming PC for well…gaming and browsing.

I have a MacBook Pro that I want to use for music production/video editing.

Is there a relatively simple way to make it all a bit easier to do all 3 of these things using the same keyboard/mouse and for work, to utilise 2 of these 4 monitors (the 34” and either the 32” or a portrait 27”) and for music use the 34”?

Gaming pc I would be using all 4.

I’ve looked at KVM switches but seems complicated and want to maintain the refresh rates (144-180).

I’ve tried Google/ai but not getting anywhere.

TIA!
