As i understood your choice is around classic French style and white theme and it shows pureness of space is considered as a value. In regard to this concept i really suggest simple cabinet doors especially those named "shaker door" for the main kitchen, but more detailed classic doors for the first floor that is showed in open area. I did not change the position of the window as I confirm the Sink position affront a window and then a Standard Kitchen triangle.
I hope you enjoy it.
