I am not sure how mise would be a "good middle ground" compared to Nix, considering it is really easy to get a static binary version of Nix. Nowadays it even works standalone without creating a `/nix` directory, you can simply run the binary and it will create everything you need in `~/.local/state/nix` if I remember correctly. And of course Nix is way more powerful than mise.
