Reviewing Bravely 1 and 2, there really aren't jobs that are a substantially different fantasy than what we already have. Mayyyybe Pirate or Spiritmaster (or Beastmaster). But Merchant would be a DoH, Valkyrie is already Dragoon, Hellblade is already Dark Knight, Bastion is already Paladin, Oracle/Time Mage are already Astrologian, etc. etc.

That said, if Bravely only got one job representing it in FFXIV, I think Bravebearer is indisputably the one the devs ought to go with. It would be the job best encouraging some sort of Brave/Default gauge gimmick.
