It probably is simpler than that - whatever racial/diversity agenda the authors may or will have is set in the story between Humans and Faunus.

That all human characters are predominantly pale skinned, in this as in practically all animated works, is more probable than not not a racial elite thinking, but an efficiency issue in drawing - a pale base can be much easier and variously be shaded against various backgrounds than a dark one, respectively contrasts better against all sorts of backgrounds.
