If you're really set on one, remember, like Freelance said, you're an adventurer. Not everyone chooses to RP their character as one, but this may be the perfect reason TO RP as one. Adventurers are described as "foreign" in some way to the city states. That could be that they're not from Eorzea, or that they're just not from the city state they arrive at. They are the ones that go against the norms, because they didn't grow up traditionally. They try new things and go new places. Miqo'tes may not be physically designed to be paladins, but that may motivate an adventurer Miqo'te to prove those who think that wrong.
