My coldest temperatures are rarely down to 0°F for my 14 mile one-way commute, when I wear the combination pictured below with cheapo fleece mittens. I generally wear single windproof fingered ski gloves though, sometimes with a thin inner knit pair. However, whenever wearing hand wear at any temperature, I also wear a pair of “wrist gaiters” made from athletic socks, to seal the wrists from any gaps between gloves and jacket.
I note that the skin of my covered forearms perspires from the additional warmth. I speculate that these wrist gaiters may further warm the blood flowing to my hands. Since wearing them, I haven’t had any hand problems, FWIW. Feet are another matter, my weakest link for winter riding.

The wrist gaiters are longer than tennis wrist bands and thus cover a longer segment of the forearm blood flow to futher warm it up, as I suggest.
