I totally understand where you’re coming from, and I’m pessimistic that any flavor of Linux will be an acceptable experience for the person you’re describing. Something like Silverblue may be least obstrusive, but compatibility will still be a prominent problem.
Alternatively, you could show them surface level cool stuff that’s easier to do with Linux. Like blocking all ads, running your own Minecraft server, downloading YouTube videos, building your own PC with cheap parts (and maybe even pirating movies and TV shows, depending on your own practices and relationship to that person). There’s a lot to love about Linux even if you don’t care about privacy and open software as abstract values.
