I'm in an 8a, and you can grow probably any sub tropical or temperate crop if you pick the right varieties. I have several "hardy" citrus with little to no protection. You can try better tasting mainstream varieties, but you will have to protect them.
Figs, pineapple guavas, asian persimmons, pomegranates are easy.
If your soil is a match, add blueberries.
Blackberries will do better than raspberries in the Southeast. It just gets too hot for them as opposed to 8a in the Northwest or west coast.
If you can manage spraying and a lot of preventative maintenance, peaches, apples, cherries, plums, apricots, can be be grown.
