Welcome to the better side! Lots of good stuff in here. Pick what you want and go from there. I transitioned to mint and put windows in a VM (virtualbox) as my “crutch”. The on thing I haven’t see is use an app called timeshift. It’s a auto backup tool. It’s saved me a few times when I tried something that in hind sight wasn’t a good idea. It let me roll the machine back to a pre-screw up state.
The other good part of this is that it let me try more things because I had a safety net.
