Mike, do you have information about the change between jup363.bsp and jup380s.bsp?
I haven't done (and probably won't do) a through analysis, but it does appear to
change Juno's position relative to Ganymede by 6.5km (PJ00) to 10.9km (PJ38).
While this magnitude change won't have much effect in most cases, it may be meaningful
for Ganymede mapping (PJ34 10.5km).

Mike, do you have information about the change between jup363.bsp and jup380s.bsp?

I don't, and not much can be inferred from the comment files. I expect that the Ganymede ephemeris could be updated from Juno flyby data, but whether that's what this is or not I can't tell.

In my experience, you have to try using two files to see if there is a significant improvement, and obviously any adjustment done with an older file may well break with a newer one.
