I'm not really in Zone 10, more like 7a VA. Not sure why that happened....

hard to give any actual shaping advice seeing as the ficus hasn't really developed any real branch structure yet. Could make a nice informal upright in a few years. I would just start a heavy fertilizing schedule starting in spring to give a bulk of growth and go from there.

The Nebari looks to be very poor from the appearance of the first image. I would consider doing a tourniquet layering (maybe where the white string is wrapped around the trunk near the base of the tree??) to give it a better even root spread, which will be important for the tree to evenly and adequately absorb water and nutrients (as well as for aesthetic reasons).
