If the chairs actually wobble the wood has probably dried out so any

Just done four dining chairs from the in-laws with loose backs and
legs. Joints fairly tight but not tight enough to stop a wobble. I
just used PVA wood glue. Did a couple here the same way a few years
ago, still solid.

Not sure that a glue that sets quickly is a good idea witha complex
structure like a chair. Something may fit well together but not quite
in the right place when fitted to the rest of the chair. Being able
to assemble and get everything into the right place for the whole is
what you want.

I'm sure there used to be something that expanded a bit after it was
assembled but I've forgotten it now.

Doesn't Gorrila Glue foam up?

It does, but the foam has no gap filling strength. If you need gap
filling then epoxy (with added filler if required) is the usual way to go).
