What I'd suggest is buy whatever meat you like, or when it's on sale, and as soon as you get home, portion it out and whatever you're going to eat in the next few days, leave in the fridge, and freeze the rest.
It's two adults here, and I'll routinely buy six pounds of ground beef and freeze some of it in 1lb portions, and some of it in 1/3rd-pound patties.
I'll buy pork shoulders when they're on sale, and cut those down to 3-4lb pieces (a normal roast here is about 8lbs), chuck roasts are frequently buy-one-get-one and I just freeze those as-is.
Same with chicken, I'll buy a whole chicken, cut it up, and freeze it in two portions; a leg, wing, thigh, and breast in each pack.
Even brats, hot dogs, sausages, I'll usually freeze those in two-per servings.
