The T-10 ticket is probably your best bet unless you're making a large amount of journeys (more than six) in one day. The T-10 gives you 10 journeys including the train to and from the airport (but not the Aerobús). Barcelona is a very walkable city and once you're in the centre you probably won't find yourself using the metro that much.
