Just in case no one comes along with a better answer; I would say it’s just too niche a use-case to expect a whole distro to be maintained for it. A super stable/popular distro like Ubuntu, Fedora, or Mint will be easy enough to use that I would consider downloading all the apps you’d need for writing to be feasible for a “non-technical” person. i.e., just as easy (if not easier, thanks to Flatpak) as doing so on Windows.
