I would guess the fact that the Crusader was single engined would be one factor. It also had some issues "coming aboard the boat". The early ones at least, were basically day fighters. (Note that a squadron of Crusaders would be paired up with a squadron of all weather fighters, like Skyrays, at least in the early days of F8 carrier operations.)
In short, probably too specialized for FAA service.
As always of course, I stand to be corrected
