When people ask me what they should grow, I have a few standard responses....
.....grow what you like to eat and will eat.
.....grow what will grow in your situation.
.....grow as much variety as you have room and time to do.
I have seen people grow lots of some particular veggie, but they don't really like eating it. So the end up giving the excess away, feeding it to their
chickens, or throwing it into their
compost pile. When I lived in New Jersey, it was zucchini. It was not uncommon to come home from work to find a bag of zucchini at the front door. Here in Hawaii, it's often bananas.
Grow what will grow in your climate and soil without going through contortions. Where I live, squash is difficult to grow, but so many people still devote a section of their
gardening space to squash. It fails year after year.
Grow variety. I have a neighbor who is fixated on green beans and pumpkins. That can become a boring diet real quickly.
If my garden is going to be a major part of my food (and it actually is because I produce most of my own food), I would grow some surefire crops, but also lots of small plantings of this and that for variety. Variety not only addresses boredom, but also adds various nutrients that a restricted diet fails to provide.
