Chezmoi strikes a nice balance between the overkill of home-manager while still being more powerful than simpler solutions.

Yadm is another alternative, the main thing I don't like about it though is that I'm not a fan of cross OS dotfiles. Having niri files on my work Mac and aerospace dotfiles on Linux annoys me quite a bit.

As powerful as the templating in chezmoi is, I think it should be considered a last resort and only used for simple files. They break your editor features like highlighting.
