I'm new to gardening. Using a raised bed and trying square foot gardening.

1. I probably should've caged or staked these before now, but I need to know in limited space how to support the tomatoes (they're getting to where they need it now): stakes alone, cages with stakes, cages flipped upside down anchored into the ground, or something else?

2. Store bought or homemade cages??

3. Do any of my other plants need support?

4. Are these plants in the best place to grow well?

Squares: I have 11 tomato (different varieties), 5 jalapeno, 1 cayenne, 4 each of red, green, yellow bell peppers, 1 purple bell pepper, 1 peanut, 1 sweet potato, 1 carrot, 1 green bean, 1 sugar snap peas, 1 kohlrabi, 1 spinach, 2 cauliflower, 1 broccoli, 1 arugula (yuck), 1 leaf lettuce, 1 onion, 1 green onion. And I have six square feet not being used.

Garlic growing around a couple edges of raised bed; the pak choy bolted fast; the beets are gone; and we have 2 squash and 2 melon plants in another part of the yard. Cucumbers are gone as well. Sugar snap peas are not coming up as well as the carrots and spinach.

In pots: herbs, strawberries, cherry tomato

Thank you for any help you can give.
