If it helps, I've been using XFCE since 2007 and it's remained functionally identical for all of those almost 20 years. It just works, it improves a tiny bit with each major upgrade, and they don't rearrange everything every couple years for the sake of justifying a salary.
Maybe it's a good opportunity to consider whether you actually have to keep running on Apple's treadmill.
I’ve combined my MacBook with a Linux desktop for about five years now. Linux has its pros as a developer, but IMHO daily driving it is like walking around with pebbles in my shoes.
Something as basic as scrolling feels slightly inconsistent in just about every app and keybindings are all over the place. There’s always the allure of getting the config ”just right” but after a while I swear I start seeing Sisyphus’ reflection in my screen.
I’d love an XFCE (or even gnome tbh) environment on a properly built laptop, unfortunately only Apple is able to build something that works in all areas that matter: sleeps when lid closed, wakes when lid opens, touchpad and display don’t suck.
