Help me choose a cake flavor!

Y'all, I am struggling with this, and we are finalizing cake flavors tonight. We are getting a 5-tier semi naked cake with chocolate drizzle, fresh berries, and fresh flowers. And even though I love chocolate cake, we don't want the cake to be dark in color. That much I do know. The hard part is choosing the cake flavor/filling combos. I can choose a different flavor for each tier or do the entire thing one flavor. BUT I CAN'T DECIDE!!! It's a summer wedding, so I'm thinking "light & fresh." Something like berries, fruit filling, cream, etc. We are not using fondant...because, gross. So, I know it'll be buttercream. But again, there are different flavors of buttercream that can be chosen. I'm leaning towards vanilla cake with strawberry filling (like strawberry shortcake). But I also like: keylime pie, banana, raspberry, lemon, etc. I just really want my cake to be a WOW factor! HELP!! What flavor combo would you pick? Any suggestions? What would make you happy as a guest? Literally any input can help me at this point, lol. TIA
