It depends on what kind of software you usually use. You should look up the programs you use regularly/can't live without to see if they have Linux versions or if they have decent replacements. If everything there checks out, find an LTS distro. Debian/Ubuntu and derivatives (PopOS or Mint) or fedora and derivatives (I don't know any fedora derivatives) would be good.
I started using PopOS last year for a gaming machine and all the tinkering I did, I did because I'm a nerd and I wanted to. If I wanted an easy experience without even looking at a command line I think I could've.
One more thing. Most (maybe all?) Linux distros can be booted and viewed in a live environment from a USB without having to erase your whole drive (just make sure you don't go through the setup and actually erase your drive (unless you want to))
I don't know anything about this show, is it a fairy tale rip off as much as the picture makes it seem?
