I am not sure if Arch or Nix are good distros if you are new to Linux.
I would say Linux Mint might be a better option to get your bearings. This is a subjective thing, but I personally found it helpful to slowly learn some core things about Linux (CLI, base system architecture, DE’s and their nuances) in a controlled environment.
Just sharing my thoughts. It’s cool if Arch or Nix works better for you.
That’s fair. My frame of context was more general.😀
