There used to be a fairly healthy sect of paladin roleplayers that hung out in Ul'dah, but time and roleplay have lead most of them away to other places by now.
The job itself isn't off-limits, but there's some qualifying first: Sultansworn are the official guardians of the Sultanate (despite never appearing in basically any cutscenes). Some quests also reveal them to be sort of city-state specific investigators; When things happen involving the crown, or some valuable artifacts, it's the Sultansworn who pursue the criminals involved and set about bringing justice.
Free Paladins aren't bound to the city-state like Sultansworn appear to be: They're simply knights who are taught the methods of combat that the Sultansworn utilize and told to go do good in the world. The fighting style was a strictly-kept secret until recent years, and while we don't know the actual number of Free Paladins out there in the world, talking to Jenlyns after completing the lv50 quest (but before starting the HW quests) will have him say something to the affect of "our numbers are on the rise!"
Whether this means other Free Paladins being taught or more 'Sworn being recruited isn't clear, so that's more room to wiggle into.
