First, I'm a sucker for anyone who uses strike-through in text to amuse the meta contingent of a discussion, so well done there.
I can't speak much to the magic classes in the game, but I can relate a little on the weaponry side of things. The first important distinction to make is that not everyone using a weapon is necessarily playing a specific class or job. You can swing a sword without being categorized as a Gladiator or a Paladin, and you can learn to fight with a greatsword without needing to be officially sanctioned as a Dark Knight.
Lore-wise, you'd want to be wary of wearing one in Ishgard as it's akin to wearing gang colors or something, but you could do it! There are plenty of people roleplaying as dabblers in a lot of martial spaces without necessarily mastering any of them. As long as you were making it clear that your character was either still learning (or just self-taught) it shouldn't be a problem.
