Endeavouros is pretty new user friendly and from what I've seen they've got a bunch of distro cheat sheets for new users, be it to the distro, arch based distro's or linux altogether. Out of all the arch based communities I've seen, most of which just respond with "RTFM", the endeavouros community has been very supportive of new users trying to learn on their OS.

I think most people recommend arch as an 'initial distro' because after the annoying learning curve involved in the initial few weeks, you can basically use any distro with ease
