The only worthwhile ones on this list are rice, cooked meats, and fast perishing fruit and veg like avocado. Freezing cooked rice and parboiled potatoes is also one of the easiest methods for good results with stir fry and potato chips and fries. In these cases you actually want the texture changes that occur in the freezer. Meat benefits the most from vacuum sealed bags and I don't do that for anything else in my freezer. Old frozen meat is also not hopeless if you slow cook it or pass it through the meat grinder.
