I acquired an old 11ft tall ficus lyrata not too much experience but it had a lot of leaf drop when it was shipped across the country from Florida to philly and has been here 18 months I just got it and had some questions about leaves and if it's concerning. Please help me.

Any advice or knowledge of potential issues would be greatly appreciated

Your plant may just be reacting to its prior treatment. But I do have a couple of observations.

First, it is already a bit too large for its space. The upper leaves are so high that they don't get much light. You may want to prune it back some because it will just continue to grow taller.

Make sure you water it as soon as the surface of the soil feels dry down a half-inch. Give it enough water so it dries out similarly again in about a week.
