Since this seems on point, I've been using mint the last few years, thanks to cognitive fatigue fighting gnome3 and KDE. What's the state of KDE w/Plasma nowadays?
Plasma has become very good especially after version 6 release with Wayland. I apply a light configuration to my setup once and then it gets out of the way. When I need to adjust something - I know I can find a corresponding setting, but I rarely touch configuration these days.
