Where should a newbie start?

I’m trying to look into edible plants to grow, as someone who can get seeds to sprout but never grow very far. In my few attempts at growing plants, I usually have to container garden, which I know isn’t great for certain plants. I’m a little overwhelmed with research.

Any recommendation for US region 5-6? I wanted to look into potatoes and squash, but I have heard those don’t really like containers 😅.
