That should've been the first mile.
There's no other adjustment that will have as much impact as switching from the stock couplers to flexible couplers or clamp-type rigid couplers. For the simple reason that all the set-screw designs unavoidably make the rod and shaft axes eccentric.

What kind of couplers are those?
After switching to a totally rigid motor mount, I found I was still getting a little wobble no matter how much I fiddled with the alignment.
The last mile for me was swapping out my rigid coupler for a flexible one (simultaneously I ditched my mcmaster-carr ACME for precisiontech which may also have helped).
Since then I don't have perceivable (to me) wobble.
If I was approaching it today, I would try one of the versions of brnrd's wobble suppressor. But at this point I am hesitant to fix what ain't broke.

But I still had some wobble. So I switched to cheap chinese ebay clamp-type flexible couplers. Made a big difference (although as I mentioned maybe it was the rod?).
