I prefer to do all my families as Face based. This way, they can host into almost anything and they can also cut into hosts while being almost any family type. Unfortunately, new users have problems using these families because of the default behavior of face based families.
I always get a call "I tried using that family but it did not work and I can only place it on the wall". I then have to tell them to click the "Place on Face" or "Place on Work Plane" every time they work with these families.
Since we only use the "place on vertical face" on rare occasions and that the current default is so disruptive, I would switch the default to a more useful and explicit option "Place on Face" rather than "Place on Vertical Face".
