Yes, I would think courgettes would be fine, also outdoor cucumbers and squashes, peppers, chillis, peas, beans and salad greens. It's a bit late to start shallots, but onion sets would be fine. NOT carrots, parsnips , chard or potatoes. Strawberries would be OK too. Some herbs don't mind it being a bit gravelly (thyme, sage, maybe oregano, chives).
