Welcome to the RPC!
Mateus is indeed the current "go-to" server for RP with Balmung and Gilgamesh locked down until further notice due to overpopulation. Omega (and Louisoix, I think?) are also RP options, but those are primarily for the EU community, I think? So unless you're playing on EU hours (or are in the EU yourself!), your times might clash with most of the RP populace there.
There are also a lot of little RP hubs here and there - Fairie, Jenova, and a few others spring to mind. But if you're looking for more open RP, I think Mateus (or Omega if EU) will be your best bet.
