Hello!
THe best advice is pretty much what Delni said. While the community is faily large as far as I can tell, the best way to see some of it would be to make an alt and try it out before moving. For a quick sample, I'd pick a class that starts in Ul'dah and look around the Quicksand. It is one of the denser areas for open-world RP that is low-level-friendly.
I'm not too sure what RP on Gilgamesh is like, but RPers on Balmung range from the completely unskilled in combat city/townsperson, to non-adventurer mercenaries, to various forms of law enforcement (Blades, Flames, Sultanswon. Seen a couple Yellowjackets and Adders), to adventurers, and there are a few who play within the Main-Story Quests as Warriors of Light. I'm sure there's a group out there who could match your preferences! (As a generalization of what I've seen, most people do not play with the Echo or Hydaelyn's Blessing, and would not be considered Warriors of Light. Something like a dungeon run or a primal fight IC would be a greater concern to such people.)
