since i do a lot of practicing into a net at home, watching my swing is very important to me. i still haven't fine tuned my eyes to see certain faults i may have when i watch, but big picture stuff i can figure out by taking a few videos and comparing them to to different videos of myself or to certain pros who i try to emulate some.

plus it's fun to look back and see the before and after.

A picture is worth a thousand words then a video is worth a million. But you need to know what to look at.

The trick is knowing what to look for.

What are the optimum positions in all three dimensions in space?

WOW!  I wish I could answer that. I would be rich.

I suggest that you go to the sand box and play.  Observe your swing arc witness in the sand and work out your front to back position.   Observe the repetitiveness of the in to out arc at various positions and work out the how far from the body ball position, but the lie angle of the club also determines how far from the body.  You also want to perfect the "lag" of the swing otherwise your positioning is a frustrating effort in futility.

Use your torso as reference points to duplicate points later.

Seeing your self on video can be very helpful for those who understand how and why any flaws are occuring, too often it sounds as though new players think the remedy for some very bad flaws can be remedied with a change in grip or tweaking their alignment in a bad position, beginers need to understand that getting themselves in a good starting position is the first key in making a good swing, being so new to the game makes the argument to get good instruction with a trained instructor imperative. I am able to catch a few of my flaws on occasion cause I have been doing this for over 30 years but even then I don't get very deep into making any long and lasting changes without an instructor.

Thanks again for your help.
I did not realize this was a very complicated problem.

ps long grass can be used as well bu the witness obviously vanishes quickly after you brush through

bonus:  My theory:   I am very right handed and in fact my natural unforced swing arc peak seems to be around my right foot. Hmmmmm?????

Could it be that truly balanced ambidextrous people have a swing arc peak near the body center and left dominant have theirs near the Left foot?   Hmmmmm?  Don't know

No. That doesn't make any sense (if you're talking about the low point of the swing). The low point should be fairly close to the lead shoulder regardless of the side you swing from.

I get the most out of video lesson summaries. I compare the before to after, and play the after prior to going to the practice range.
