You won't find snowflakes at FRF...
As for your question on winter traction, I'd suggest pouring over the reviews at the big online tires sites. There is no treadwear ratings required for LT tires so compound is a bit of mystery.

KIDDING !
For mall crawling, any of these tires will do, but the braking could really change the truck feel if you go up significantly in weight. I’ve swapped wheels and tires before on my Mustangs, and my bikes. by far the biggest difference I saw was putting carbon fiber wheels on my zx10r; The rear wheel was 6 pounds, the front well under 4 pounds, each was well more than 50% lighter than stock.
I didn’t really appreciate the easier braking but I can tell you that the wheelies came on a full 1200 RPM sooner. That’s an exaggerated example for sure, the whole bike under 430 pounds. I think to notice the impact on braking it will take more than 5 pounds / wheel, but that’s just a guess.
My thought is that it’s not just any one thing; stiffer sidewalls and load rating will or should make the ride characteristics a little more harsh. Longer lasting might not be conducive to good pavement traction.
Anyway, as you said, you have time. consider what you’re going to be primarily doing with the truck and you’ll be fine.
