Why not EndeavourOS? It's based on Arch Linux, with minimal numbers of external packages; quite unlike Manjaro actually. You can just treat it as a standard Arch install, and even use the ISO to boot with wi-fi drivers and all and install Arch plainly, without the non-wifi and other regrets. EndeavourOS is pretty great; I personally use it as a live-ISO (XFCE environment) and just install Arch from within the live EndeavourOS booted iso. Just throwing it out there.
