Most economical balance would probably be BART to Embarcadero Station then UberX the rest of the way.
You can take the Muni F streetcar line from right above the Embarcadero Station but it is almost always full of people and slow, so not a great experience with luggage.
There are shuttle vans (SuperShuttle, etc.) but it's a long, thankless, unreliable ride.
