You can setup your Arch with grub menu btrfs snapshots just like NixOS for convenient rollbacks. NixOS has too steep a learning curve, coming from someone who recently tried it and ended up being somewhat disappointed by it. NixOS sounds good on paper but in reality it is a long way from a mature product for desktop or general use.
As you mentioned Arch has AUR which packages just about anything and everything you could ever want in the future. And the Arch Wiki will never be “not relevant” so long as you are using Linux anywhere, the Arch Wiki is a handy reference.
