Part of it will also depend on what skills you want your character to possess and how those translate into the Lore of the world. For example, it is not difficult to make a character who is a Paladin, because by lore the Sultan-Sworn broke from tradition and began offering adventurers the opportunity to learn their ways and serve the realm as, 'Free Paladins.'
By contrast, White Mages and Black Mages are the extinct jobs of ancient nations which began a war so devastating to the world that their arts drained the land of so much aether that it caused a Calamity to plunge the planet into the 6th Umbral Era. There are White Mages today, but they are few, carefully controlled, and entirely of a non-playable race, the Padjal. The only exception is the Warrior of Light. There are also several wielders of Black Magic in the world, but they're primarily outcast Beastmen and a few people dismissed as lunatics. If they were known as Black Mages and actively wielded the art they'd be arrested, tried for criminals, and executed.
So I'd advocate thoroughly researching the lore of any class you think you'd like your character to be. Most you can, within reason, create a workable story around, but Black Mage and White Mage are the big two offenders in the various RP communities. At least, they are until such time Square decides to write their lore as moving in a direction where they are a bit more tolerated and more are being trained. Which might happen in Stormblood if we're lucky, since Red Mages used both White and Black magic.
