Does anyone have a recommendation how far the mount should be offset for

That would completely depend on what airframe you're putting it on.  The offset is incorporated for a variety of reasons, some simple and some very complicated, with the goal of having the airplane fly straight at cruise speed, or maybe not need so much rudder on climbout, or to have the airplane respond correctly when the engine is firewalled on a go-around, or ... or...

It all depends on what the designer was trying to accomplish and how the thrust line and torques vectors fit in with the rest of the airplane.
