Hi Greg. I use Blum 39c hinges, usually. They are 1 1/4″ overlay for face frame applications. All your points are valid but I don’t find that the restriction on the opening side to be excessive. It’s only an additional 3/4″ on each side at the frame. The inside of the box is not reduced so the storage capacity is the same regardless of whether the face frame is narrower or not. I’m self taught and this is the system I came up with years ago, the origins of which I don’t really remember.
