We have one friend with a heated floor in his shop that is incredible and another with a heated floor SE of OKC. Both said the cost of installation was a little high, but the benefits paid for it in comfort.The most awesome floor I ever experienced was in the home we rented for 4 years in Germany. It was terracotta tile with hot water radiant heat. If I ever build a home outside of the AZ dessert, I'm voting for ceramic tile and electric radiant heat in bathrooms (if compatible). We currently have engineered hardwood in most living areas and the kitchen, carpet in bedrooms (dislike both for different reasons), and sealed stone in the bathrooms (really sensitive to scoring by acids).
FWIW: I voted for "Hardwood of some sort" with ceramic "hardwood" in mind. Consider looking into radiant heat.
ETA: By radiant heat, I meant "makes the tile warm in the winter to treat your toes"; not to heat the room, like the home in Germany.
I seriously doubt we will ever build a new home but if by chance we did, it will have heated floors.
