There are no such things as run levels in systemd but yeah desktop 
related services should just be enabled when booting into the graphical 
target.

Arguably sshd and nfs should be disabled by default as well and  [1] 
mentioned avahi is enabled by default as an specific exceptions FESCO 
should update that wiki page with the arguments on why these services 
are granted exceptions of being enabled by default.

Personally I'm of the opinion that non essential services should not be 
enabled by default.
