then all your pistons and rods could be the same length and they would still be at diff measurements from the deck now wouldn't they...

Yep, understand & agree.

I still would like to know how much "piston deck height at TDC" variation is typical or acceptable among the cylinders.

Or is keeping the volume above the piston the same for each cylinder more important than keeping the heights the same (yes, these are related, too)? Thanks!
