I generally set things up in a few camps:
Goblinoids, including all the orcs, trolls, bugbears, bogeymen, and etceteral.
Humanoids, which include all the elves, orcs, giants, guys made of fire, etcetera.
Dragons, which include all the kobolds, owlbears, monstergirls, and anything else that is blatantly magical in construction.
