I also read something about the steering column needing disconnecting to let the subframe droop more. Driver side is not as low as passenger. But I’m not real clear on how to do that and associated risk to the clock spring. Any other tips are appreciated. Thanks.
Make a mark with whiteout on the steering coupler, there's 2 10mm bolts holding it on to the tq sensor loosen them and it slides right off.

As long as you disconnected the power steering connector, if you don't you can damage the cable when you lower the subframe.

Dropping the subframe 3”, I never had a problem leaving the steering rack attached, bolt removed gives the spline enough play, movement. Sounds like maybe your friction disc alignment was off abit.

Current update on the car after the clutch job.

The morning after completing the work, took it for a drive and all seemed normal. Today, we are experiencing some driveline vibration when under 1/2 or more throttle. More intense as revs rise and does not vibrate with coasting. Shifting is fine and feels generally normal. Given that we did not mark the driveshaft when uninstalling, was thinking maybe the driveshaft is in the wrong orientation. Looking at videos I can see that the end of the shaft with the raised metal stamp (on the outside) goes to the diff, but unclear on how to properly clock it when installing.

First: Do you all think the vibration is likely the driveshaft?
Second: Any chance the vibration could be something else (i.e loose flywheel bolts, etc?) based on symptoms.

I don't hear any grinding or feel any problem in shifting, just a strong vibration under acceleration. Note that we changed motor mounts and trans mounts as part of this process (stock). Thanks for the help S2k forum.

most people don't mark the driveshaft when removing it so it's unlikely to be the clocking of the driveshaft

your symptoms sound like the very common CV bucket vibrations are you sure it wasn't doing that before the clutch replacement?

i thought of that too. But all was fine prior to the clutch job.

Driveshaft orientation/marks do not matter.

I think your problem all along was misalignment of clutch disk. Clutch alignment tool wasn't perfectly centered. I had this same issue doing mine, and had to drop trans again and redo the alignment tool.
