Dining Room Dilema

Our dining room is a hard room to decorate for me. It has vaulted ceilings so it is difficult to create a balanced look, on one side of the room the ceiling is 20 feet high, while the other side is only 9 feet. The other challenge is that the living room and dining room are one big great room. The good news is that I pretty much have a clean slate to work with, the only furniture I have is an antique buffet I painted white and my two new wingback chairs. I have a few ideas on how to approach it, but I am on the hunt for more.
We have so many options: bench seating? upholstered chairs? which style of table? I am not sure which direction we will go yet, but we are excited to start the journey!
