I, like @Acre4Me, use a section of fence for vining plants just held up with a tpost.
I planted onions throughout the garden to help with pests, some dont seem to like onions.
I love to see all the garden plans! My garden is probably going to be drastically different this year as I'm facing back surgery. I'm hoping to do a lot of vining plants so I wont have to bend over, so cukes & squash. & just a few tomatoes. I think its going to be very simple, sadly.
another good thing to do is plant cover crops! Or a few rounds of cover crops for green manure-till under before fully mature or producing seeds. Of course, this will require a helper, but it’s hard to mess up destroying plants and turning it under, so even a bored local teen can do a good job and earn some money.
we planted pole beans (for drying to use later in soups, etc). This could be a good option as they took longer to grow and you need them to dry out, so no stress in picking them while fresh. Also grew black beans for drying, but these were a bush variety. But, just had to pick when dry! The harder part of the bush variety is they sometimes got blown over, and then the pods were touching the soil with higher incidence of mildew like spots from drying, yet touching moist ground.
hope your surgery occurs after planting time, so you can watch a few things develop. sorry you have to face back surgery!
