I grow a fairly large garden at an environmental school and designed it as an urban victory garden. The produce is used by the school and for educational purposes.
I have some fenced in areas but mostly I grow the plants inside old tires filled with dirt like a raised bed and inside 5 gallon buckets. These are things you can do in an empty lot. Around the buckets and tires are a round wrap of very high stock fence which acts as a barrier to keep the animals off the plants plus gives the plants support as they grow. Great for pole beans, any other vine plant, cherry tomatoes and other tomato varieties that are very leggy. Smaller plants like peppers do well in the buckets. Drill holes in the bucket to drain water about midway from the top to the bottom. This keeps the roots moist but not water logged and keeps a water reservoir in the bottom half of the bucket for dry periods.
Bush plants are planted inside larger fenced in areas so they can spread out better. Squashes of all kinds, etc. I have a large pumpkin patch in a field that is fenced in and the plants are in raised beds scattered through the impoundment. Had nearly 50 pumpkins this year.
I have another fenced in area with raised beds made by taking two 12' long, 12 inches high, 2 inches wide board and screwing them together length-wise to two end pieces about 18 inches wide. These are filled with topsoil I have delivered and dumped onto my compost pile. I plant lettuce, onion, and herbs here. I also have a flower garden of zinnias, cosmos, flox, bee balm, etc. Basically easy to grow flowers for cutting.
Tons of tomatoes, decent peppers, squashes, pole beans, salad veggies, and pumpkins. Flowers got chewed off by deer and never came back so I need a higher fence. Deer and bunnies get blamed for a lot of garden damage but ground hogs, voles, mice and other small ground animals are the worst. Ground hogs can climb a fence to get into a garden or just sit up on the stock fence and eat beans, tomatoes, etc. Fortunately we have a resident Fisher and some Bobcat that eat the ground hogs for control. Next in line are slugs and snails which eat the fruits, flowers, vines, etc. Other small bugs like striped squash beetles which eat any vine plant, etc. do extensive damage. I would take dealing with deer over all of the other pests if I could.
