Canon Fruits will be allowed! There's a small number that will be hard banned (the Gum-Gum fruit, the Dark-Dark Fruit, and the Op-Op Fruit, due to canon importance I'd rather not put on the table right away), and I currently have no canon Fruits reserved for NPCs. My hopes is that anyone applying with a canon Fruit will aim to use it in a way all their own, be it developing its abilities in a sensible but interesting direction, or it being so fitting to a character that nothing else makes sense. I'll also be a bit apprehensive towards Mythical Zoans. But with an interesting enough character concept, I think I'll be comfortable with just about anything!
