Autovacuum will eventually free your extra pages regarding index bloat but it takes multiple runs.
You could also use reindex instead of vacuum full since you are only interested in the index.
For the table there may be other options but they depend on your pattern of writes.

I have a large table with numerous indexes which has approximately doubled in size after adding a column - every row was rewritten and 50% of the tuples are dead. I'd like to reclaim this space, but VACUUM FULL cannot seem to finish within the scheduled downtime.Any suggestions for reclaiming the space without excessive downtime?
