You're a little north of me but we should be fairly similar. My spring garden will have onions, peas, cabbage, cauliflower, broccoli, carrots, beets, chard, kale, loose leaf lettuce, mesclun, and spinach. I'm sure I'm forgetting something. When the ground warms up I plant corn, beans, tomatoes, peppers, eggplant, okra, black eyed peas, squash, maybe melons. Sweet potatoes do great. I start garlic in the fall for summer harvest.
For herbs I have oregano, basil, dill, cilantro, thyme, chives, and parsley. I may have finally gotten some rosemary to live through the winter. We'll see how it handles this cold snap. Mint is in a corner next to a workshop where I can keep it tamed by mowing any that dares try to spread.
I don't do much for flowers, mainly zinnias and marigolds. Lantana is a nice annual for me here, it takes our summers pretty well. Black eyed susans are like a weed, they self-seed everywhere. From bulbs I have daffodils, iris, and gladiolas. A few lilies too.
I think you have a lot of different things you could do well with.
