Damn B that's a big ass garden.
We're on our 3rd year of gardening. We have 2 small raised beds, about 25 square feet each. We had planned to expand to a couple more beds and relocate to a different part of the yard, but we were too busy with other stuff to make it happen. Next year perhaps.
This year we have a few jalapeno plants, a couple cherry or grape tomatoes, not sure which, 2 varieties of cucumbers, one of which will become dill pickles, and I think 4 broccoli. Also a couple strawberry plants in pots on the patio. Need to come up with a better plan for those, although they were more of an experiment this year.
We had a couple of seedless watermelon plants last year, and in all honesty they weren't very good. They tend to overrun everything, and you have to water the shit out of them, obviously. I'm not a big fan of watermelon in general so I could really care less, but the wife and kid said it was kind of mealy and not sweet enough.
I'd like to do corn at some point, but I need to do some more research into it. My understanding is that you need basically males/females so they cross-pollinate, and there's a minimum number of plants you should grow. That would probably have to be an additional bed or two on it's own. I have a pretty large compost bin that we tend to regularly so good rich soil is never a problem.
