Not even close, if you actually install barebones arch, then barebones arch is exactly that, barebones. You wont even have a DE.
Endeavour is what you want. It’s just straight up arch, but with all the stuff you’d want to set up anyway done for you.
And if you want an “app-store” style app to browse packages with, and not fiddle with the command line to manage packages, install pamac. It can be expanded with AUR and flatpak support.
