Which stop to get off at on Tri-Rail WPB to Miami Beach ?

Hey everyone, I'm in WPB visiting family, and heading to Miami later today via the Tri-Rail train. I'm still a bit confused on the best stop to get off at, is it "Metro Rail Transfer" , "Miami Airport" or "Miami Central " ? I'm staying on South Beach , and not sure which is the closest stop. I dont really plan to transfer trains (unless it's painless) , I just planned on getting to the closest station and getting a Uber to Miami Beach. Help would be appreciated!
