Thanks again everybody for all your input, it's definitely helping!

It looks like I will go for the cheap solution.... Ortlieb's :-)

I would love to see a physics analysis behind that.

Sort of...Some of the Ortlieb bags are rolled closed like dry bags. The surface that faces inboard towards the bike generally has something inside to stiffen it like a plastic sheet to prevent it from going into the wheel. Usually there are two or three hooks attached to secure the bag to the rack - 2 upper hooks to hold the weight and a lower hook to prevent the bag from swinging out sideways.

With panniers on the front, the panniers are near my hands when I stand up and pull on the bars. This means I don't have to twist the frame as I do when the panniers are instead on the rear. I discovered this in the summer.

Thanks for taking the time to explain, Jsdavis.

OK, OK, I don't know how to do this. Does it make any sense at all to you? Can I improve my description? I was surprised at what an improvement it was, especially since I expected no improvement at all.

The fork on most bikes only flexes fore and aft, not laterally, so maybe that is what you are experiencing?

I'm experiencing the lack of frame flex. The more weight on the back, the more the frame flexes when I stand up to pedal.

I can't "even"....

You mean the rear triangle follows the bottom bracket/seat tube more cooperatively vs with stuff on rear rack? My old cruiser had quite a bit of frame flex, with no racks of any kid, but it was ALU with big diameter tubing, are you using alu or steel? Narrow or big tubes?

Yes that's right. It's a 1982 McLean with Reynolds 531 tubing, standard diameter.

Get the fattest, largest panniers that exist, and you'll likely be hitting your feet against them, sure. But if just commuting, you can generally get by with panniers smaller than the larger, typically rear-oriented bags. Such as, going down from the Ortlieb Back Roller bag to the Front Roller bag. It'll take up less space, be less likely to strike.

If you have size 15 feet like, that bolded part is super important. 415mm chain stays aren't going to cut it! I suspect I need a full on touring bike with 450mm+ chain stays to avoid heel strike.

I always have heel strike-even with panniers shifted all the way back on my rack. Which is why I use a trunk bag. Topeak MTX TrunkBag DXP with Expandable Side Panniers fits a change of clothes, iPad, and lunch with no issues.
