You’re probably selling yourself short on the tech front and over-estimating the difficulty of installing something new. If you wanted to install something like Linux Mint or Fedora, the most complicated step would likely involve making a bootable thumbdrive to load it from. You could check that all your hardware works as intended (ie, can you connect to wifi, does sound play properly, can you watch a video on youtube, etc) without actually modifying your base OS, and if it does, the installations mostly hold your hand and you can get a perfectly sane setup just sticking to the defaults for most things and clicking next. There are plenty of options out there where you don’t need to be a command-line wizard to have a perfectly usable system.
