Bit off a dreamland, but if I did have friends/family move to Linux from windows a distro with easy checkpointed rollback would be ideal from a support perspective, but agree it's more of a niche / industry concern then a non technical home user thing
Might be worth looking into immutable distros (nix, guix) and their home management systems, or containerised apps (flatpak, where you can inject config). A lot of tools are hardcoded to non standard locations so it's kind of a losing battle by default. A similar strategy would be to use permissions or mount certain folders as read only.
