The Nix binary cache does x86_64-linux, aarch64-linux, x86_64-darwin, aarch64-darwin and maybe others. Every single package is different, but built from the same source. You won't be sharing binary cache even for python or other interpreted things since they depend on "stdenv" which contains bash. But in practice it's really easy. Though if you're all into robustness you should probably test on the same arch you deploy to eventually.
