My impression of Campbell is that he does not meet your definition of an occultist, because he does NOT believe that "the 'key' is hidden and available only to trained initiates." Certainly, I see no indication that he believes there is a specific secret with an empirical answer that he, as an initiate, has access to by reason of his understanding of clues.
Rather, he seems to believe either: (i) that there is no "key" presently available (if "available" means being accessible merely by adhering to some pattern or form established by others), or (ii) the key is available to everyone but, for the most part, one person's key will not work for another, and must be discovered through communion with the experience of being alive.
Put a little differently, he appears to be more of a modified Nietzschean, advocating that the way to find the "key" is purely individual (although, unlike Nietzsche, he seems to allow that, for some, that "individual" way may involve choosing a traditional, perhaps traditionally religious, path.)
