You won't believe this but I have a fancy-finned goldfish that will
display swim bladder symptoms if I feed him anything but frozen
veggies (thawed, of course).

This is almost certainly constipation, not swim bladder. Constipation
is real common in fancies because of their short fat round bodies--
the digestive organs aren't as efficient because of the shape they are
confined in. There are lots of opinions on how to treat it.

Some other options: No food one day/week; alternate the types of food
regularly between veggies and other stuff; try feeding just once a
day. Keep feeding those veggies if they keep him normal.

Also watch out for high nitrates-- they can cause floating issues.
Good luck.
