Cabin crew will use the term "licenced" and "Flight Deck", pilots tend to dislike these phrases, probably in the same way that crew dislike the terms "legacy crew" or "heritage crew" and are now trying to introduce this "first crew" phrase. Ranting about them will not change anything, these phrases will continue to be used especially when it is realised that some people get irritated by them.
The term that is probably most apt for this situation is qualified, as in "Cabin crew are qualified to fly on three different aircraft types". However, knowing that will change nothing.
