So, I'd put DIN valves on all the tanks, and buy SS DIN plugs, and put those in them as well.

Why would a yoke valve be at higher risk?

If the valve seals were to fail would you really want the pressure waiting behind a plug?

FWIW mine go in the basement but my gas grill cylinder does fine on the porch for all 12 months here in Maine.

I've got two bathrooms. I need only one. Tanks and gear go there when I'm not using them.Tanks in the bathtub and other stuff hanging in the shower stall. But I go diving in the FLorida Keys every month so there's really no reason to 'store' them. If I didn't have the second bathroom the tanks would go under the bed in my second bedroom and the stuff in the closet.

No higher risk, but I don't know of any product that will effectively prevent gas from leaking out, other than leaving a regulator screwed on to the tank all winter, for yoke valves. But DIN valves have a solution.

Yes, I'd rather have the pressure held in by a secure plug than have the tank drain and discover it empty in the spring. Most likely, when the tank warmed up just a tad, the seat would re-seal, and removal of the plug should not be an issue: as soon as you get it slightly loose, the miniscule amount of air left in the valve will expand and drop in pressure, so you won't have a rocket on your hands at all.
