Anything outside of the stuff required to make a graphical desktop work?

No? Wayland is available but Xorg is the default.

FreeBSD doesn't install a display server on default so the choice is yours.

There is no GUI installation of FreeBSD so I am not sure what "linux parts" you are referring to. The installation uses curses which is ancient and has existed since the dawn of C, Unix. Abd what FreeBSD is. Is that what your referring to?

pkg is FreeBSD's package manager.
