I’ve been in your shoes a few months ago. I tried a few distros in VMs and ended up using OpenSUSE Tumbleweed. It comes with different GUIs and I decided for KDE. As a beginner TW helped me with the built in snapshots mechanism. So before I did anything, I took a snapshot, did it, and if I fucked up, I could easily rollback and try again. Since TW is a rolling release, I now make a snapshot before and after the system update So I always have some stable Rollback snapshots. Gives me so much safety to fiddle around and learn more about Linux. Been loving it so far.
Make heavy use of ChatGPT. I’ve been chatting about Linux with it for months now.
