What cake flavor should I make?

My 22nd is coming up, and I want to make (or buy) a birthday cake, but I’m lost on what flavor. Weird question, but I have no clue what cake flavor I’d like. I’m the type to just eat vanilla everything because I know I like it, but it feels too simple.

I’m not too big on fruit in cakes. I enjoy a lemon cake w/ curd but one of the people who’ll eat the cake dislikes curd. I like orange as well, though never had it in cake form. Love me a cookies and cream or cookie dough flavor. Not big on too much chocolate, acid reflux is fun. Not into coffee, nuts, or anything overly sweet. Open to really any suggestions, I know nothing about flavor combinations lol
