@minicx What's the reason for installing a DE alongside #AwesomeWM? Is it just for a file manager, terminal, etc? Could be those are better installed separately vice a whole DE for a few programs. There also may be similar programs that suit your needs that are not part of any DE.
@minicx#PipeWire service should be fired up via services management and depending on how void sets it up, there may be something you need to launch when the wm starts. AwesomeWM uses ~/.xinitrc for auto-starting programs.
If you're worried about each user's initial $HOME configuration, /etc/skel/ is where you can throw that base xinitrc and any other configs you want every new account to start with.
I know nothing about #vscodium, sorry, can't help in that department.
Automounting could be handled quite user-frienlyful by udiskie, it has a tray icon to make things easier. I'm pretty sure the Thunar volman plugin is also able to handle this. You don't need all of #xfce for #thunar.
