Easy answer - however not one that is quickly answered. Possibly the information below will help you - since I'm on perma hold with Cox Cable this morning.
Let's talk in terms of the "pure" "simple" theory - "outside" of any particular practical golfing example - just to understand the basic principle at play.
First let's clarify the concept "CF aligning". The broader principle is that it could be any straight line force through the longitudinal center of mass of the golf club. So similar to just a golf club swinging in a circle with the pull straight out through the longitudinal center of mass i.e. sweetspot. Let's look at an example that you can see. Take a sand wedge and a 5 iron and hold each lightly at the grip end with thumb and index finger - shaft hanging down towards the ground - that straight line force - gravity in this situation- pulls through the center of mass and aligns each club. The sand wedge leading edge is more closed than the five iron because of the construction of the clubface is different (wider)i.e. more mass behind the leading edge. Likewise, rotating these clubs in a circle would automatically align their club faces - differently but consistently. So you could rely on that principle to consistently align your clubface.
If there wasn't other issues at play as in a human swinging a golf club - for instance if you just had a golf club swinging around a centered rotating pole - attached by a rope say and moving fast enough where the shaft was parallel to the ground - then based on the way they construct golf clubs - you would always have the face closed to the motion of the clubhead at any time and therefore if hitting a ball - you would always produce a draw shot.
This issue of CF aligning the clubface relates to Homer's "Hookface" definition.
Regarding the highlighted part of your post. Let's say the CG offset produces a 5 degree closure of the leading edge. Using the plane of motion as a zero reference the leading edge will be 5* or 95* closed ?
