No indication of bloat there. You could afford to free some RAM by
reducing the max_fsm_relations setting. (You have 39 relations but
are reserving RAM to keep track of free space in 5000 relations.)

I'll see what I can glean from that when I get some time.

That's not usually a problem.
The other thing I was hoping to see, which I don't think you've sent,
is an EXPLAIN ANALYZE of the same query with the settings which you
have found which cause it to pick a faster plan. As I understand it,
that runs pretty fast, so hopefully that's a quick one for you to
produce.
