From your list, I think I'd choose cabbage and bok choy. And then next, I'd choose potatoes. That's sad. I figured I should choose something that I enjoy in various forms and cabbage / bok choy, and potatoes are the only ones really.
I don't particularly like raw spinach, broccoli, or carrots but I love them when they're cooked until they're really soft. I don't like beets, cucumbers, pumpkin, or zucchini, but I'll eat them. I love raw tomatoes, but I hate cooked / sundried / roasted ones. Turnips are kind of flavorless to me. I love sauteed / grilled onions, but I hate raw ones. I've only had squash pureed, in baby food (gerber / beech nut brands) and soup. I like eggplant and lettuce.
Tl;dr: I think my favorite vegetable is asparagus :}.
