I'm personally in the camp that it isn't a great idea to ICly tie yourself to a Job like Dark Knight, Dragoon, Paladin, etc. unless you're wanting for it to be a central part of the character.
When you bind yourself to in-game Jobs (and classes, to a much lesser extent), and you also plan on making an effort to stay mostly true to the game's lore, you're shackling yourself to the will of the game developers and may end up in a situation similar to what a bunch of IC Dragoons ended up in shortly after the lore book came out.
So just because you want to wield a big sword doesn't mean you have to be Dark Knight, and just because you punch good doesn't mean you have to be a member of the Pugilist Guild. Heck, you can wield a big sword and punch good if you want, and still not be bound to any particular in-game Job.
