Help! I need to find an amazing buttercream or cream cheese icing recipe for wedding/birthday cakes. ?

I love Publix buttercream in Florida, I am essentially looking for a recipe from a proffessional cake decorator, that is not too sweet, but is light, fluffy and tasty. Any help will be greatly appreciated, as I am in a time bind
