Generally speaking, many gameplay elements don't necessarily translate to narrative/lore/what-have-you. This is one of those gray areas. I'm not at all surprised that you didn't find anything on the subject, because unless I'm mistaken there isn't anything to find.
My personal approach is to look at a character's capabilities. Is Character A capable of X, Y, and Z? If yes, are they always / should they always be capable of X, Y, and Z? As an example, I find myself against the concept of cure-slinging pugilists on the principle that any such character would have needed training and/or inborn talent at conjury in addition to their physical skills. If a student from Stillglade Fane traveled to Ul'dah and attended lessons at the pugilists' guild, though? Fair game!
Cross-class skills from job subclasses, IMO, make far more sense as guidelines for in-character capabilities than cross-classing as a base class (which basically lets you take anything from ANYWHERE, hello Blizzard II casting lancers).
