Your definite list is way to large. I would maybe think about the definite list above 100g.
Think about 2 clowns (there are no nemo fish in nature), 1 chalk basslet, 1, scooter blenny or 1 algae blenny, and maybe 1 yellow tang. That would be my entire list for acceptable and responsible fish husbandry from the list you provided. You could keep inverts and some easy to care for corals with this setup as well.
Other wise you might go entirely predator tank and try 1 dwarf lion like a fumanchu and 1 snowflake eel with nothing else in the tank fish wise. Few inverts as they might be eaten and no corals.
