I shared your concern with letting Nix manage all configs because it felt wrong to me to have an abstraction layer over all kinds of configs. I've later realized that's got a big benefit of being able to use values across various configs, like high DPI settings for specific machines with 4k monitors as an example.

Version controlling Nix expressions is trivial since it's all just text files. So i basically use just git for that. With flake lock files you get a pretty high guarantee that rebuilding your configs (or machine setup) will be quite reproducible.

I should add that I do still have some imperative/manual steps still though, mostly setting up doom emacs.
