The only reason I went with manjaro this last time is because I had my arch Linux install adventure already and I just wanted my computer to work. is there an install script that just works now?

In addition to what has been mentioned already, Garuda is an Arch derivative where convenience is the whole point. No install scripts, just your usual live ISO with a Calamares installer plus a bunch of convenience utilities once you’re set up.

It’s not exactly lightweight by default but it does make for a very comfortable Arch experience.
