My short answer is that I mostly just use whatever is easiest to get, but having tried almost everything here is my prognosis.
Uncured fat doesn't store very long and consequently adding it to ground meat reduces the time before it starts to change flavor in the freezer. I can use year old no-fat-added game burger without noticing any flavor change. So, I don't usually add any fat to plain ground meat, but beef would be my first choice because it will store longer. Cured bacon also works great if you can get it cheap since the cure adds storage life.
Fat really is pretty much necessary if you're curing (salami, jerky, etc) or planning to eat without mixing into a dish (brats, sausages, patties). For these preparations I prefer pork - and usually go with cured bacon to extend freezer life. Pork has less saturated fat than beef, which means it is softer and blends easier into the meat, and consequently fries better because it liquifies more readily.
