"entirely possible" is a bit of a stretch. You can install some hacky WM and sketchybar but system settings, workspace three finger scroll speed, the finder app, window chrome, login screen etc are not something that can easily be changed. And the default apps are really not that great for power users. Calendar, Mail and Finder are all slow, dumbed down and only very superficially customizable. I daily drive an M2 Pro MBP and I was running a Linux desktop up until 2 years ago and I felt like there were barely any limits to customizing the latter while I have to fight macOS at every step if I want to do something that apple does not want me to do.
