I have found the exact opposite to be the case. In 2012 I have made about 45 cakes (around 40 weddings and the rest other occasions). I can only think of 2 brides that picked one of their tiers to be yellow cake; neither bride had regular buttercream filling (one had pineapple and one had cherry). Now, chocolate is a regular option brides pick, but I haven't done any this year of a chocolate/regular buttercream combo. I have had a lot of chocolate with raspberry, mint buttercream, or white chocolate ganache.
In my experience since I offer what could be considered "out side of the box" flavors/fillings most people want to try something different. I always recommend to brides that they should have 2 or 3 options for guests when it comes to cake flavors and fillings (it depends on the guest count if I recommend 2 options or 3 options)(I don't charge extra for someone picking more than 1 cake flavor/filling per tier) so if someone doesn't like raspberry, for example, there is something else for them to pick.
At the consultation I hand out a 1 page list of suggested combos for cakes and cupcakes (they are interchangable). The client does not have to pick anything from the list but because I offer so many options, it can feel overwhelming to pick what they want. The list contains more "out side of the box" ideas - in other words, no yellow cake with buttercream filling. To me, that isn't a very memorable combo and I want people to remember the cake they ate at their cousin's wedding and come find me for their wedding :)
