I am no programmer either, mainly a technical-oriented user, and I made the switch to a linux-only desktop almost 20 years ago. I tried several distros but I keep coming back to ubuntu (in vanilla gnome mode), with it's closeness to debian and huge library of apps, with it's massive userbase you get a lot of online community support, and it's really polished these days. For the last 5-6 years or so I've been using "LTS" releases, doing major updates every two years, I found that to be a very reasonable cadence and it gives you great environment stability. The only significant downside I found these days is ubuntu's insistence in using their (proprietary?) snap desktop container app ecosystem, I personally much prefer flatpaks, and actually I use flatpaks extensively on my ubuntu desktop for SW that needs frequent updating (darktable, logseq, etc)
