Cake Flavor / Fillings

Y’all I am struggling with this, We are getting a 5-tier semi naked cake with fresh berries and fresh flowers with greenery, I do know that we don’t want it to be a dark color. 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 spring 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 almond cake w/ strawberry fruit filling & a white amaretto cake with another fruit filling .. 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
