What about Kicksecure or Whonix (based on kicksecure apparently)?
I hate to say this, but if regular linux distros aren’t secure enough for you, you don’t want to use MacOS, and you’re not tech savvy…perhaps you should use Windows, but take as many measures to protect your privacy while using it as you can.
I was in a similar situation and discovered that the best way to get around this issue is to compartmentalize: personal web browsing on GOS, development on laptop. This was the best option between very difficult to use Qubes and bad, bad Linux desktop security (worse than Windows, MacOS). The mobile experience is infinitely easier to manage and at the same time the most secure. The only security feature that any Linux distro (other than Qubes, Whonix) offers is fast updates, and for that you can just refer to PG’s recommendations.
