Rotating annual polycultures

What are some good, tried-and-true annual vegetable polycultures for zone 1 garden beds? Zone 7a, southeast Pennsylvania.

I have read about a few of the more standard successional and companion crops people have tried, and it's an intriguing approach, definitely more interesting and I can believe it's both more productive and self-sustaining than the usual annual beds with just a few companion plantings apiece. I've also used rotation for the standard 4 annual veggie categories (legumes, roots, brassicas, nightshades, with a little companion overlapping) around some beds on an annual basis. But figuring out polycultures for each bed and in rotation sounds more complicated!

That said, I will have six 4x8 garden beds to work with, and I'm currently building deer cages and trellises for them. I might set aside a couple of them for propagating perennials for the forest garden, but I can see reserving ~4 for the annuals for the next few years, and I can also easily rotate those beds year-to-year for pest control/confusion. I do also plan to add some perennials throughout for herbs, additional vegetables, and insectary support. So, maybe ~4 within-bed successions would be good? Open to suggestions!

I've been doing something similar in 7a for a few years now, mostly working out which combinations actually play well together rather than just theoretically complementing each other. The one that's worked best for me is a summer bed of climbing beans, squash and lettuce underneath, then flipping it to a winter brassica and broad bean mix once the summer stuff comes out. The beans fix nitrogen for the brassicas coming in behind them. Main thing I've learned is that timing matters more than the actual species pairing. If one element in the polyculture gets a head start and shades out the others before they establish, the whole thing falls apart. Starting everything at the right relative stage rather than all on the same day made a big difference.

This makes sense. The timing considerations can be complicated, so I'll probably start simple. It seems like legumes are going to go with everything for nitrogen fixing, and root veggies can also share with everything else. Perennials and biennials will mostly stay put. It's the brassicas, cucurbits, and nightshades that I suppose I should limit and rotate more for nutrient use each season.

My current thinking is that I'll anchor the polycultures around the plants that need more space from each other. So, tomatoes, peppers, potatoes, cucumbers, melons, and broccoli/cauliflower each should be more or less separate from each other for space and nutrient use. Then everything else I would want to grow (beans and peas, greens, alliums, carrots, radishes, and all the herbs and flowers) can be built into the polyculture guilds. Maybe not corn (not super practical in smaller beds), but I know it works to substitute sunflowers in the three-sisters. I'll do some more research, and report back!

Some ideas:

Broccoli and  cauliflower guild  (rotation 1):
Broccoli, cauliflower
Beets
Celery (if planting)
Green onions
Garlic
Swiss chard (perpetual spinach)
Cilantro, dill
Nasturtium, marigolds, nectary plants
Pole beans, peas (trellis)

Cherry tomato and cucumber guild (rotation 2)  (the beds are 4x8, so this will be within one bed but they should be far enough apart)
Cherry, maybe full tomatoes (outside half)
Cucumber (inside half) (trellis)
Bush beans
Green onions
Garlic
Radishes
Basil
Parsley
Nasturtium
Sweet alyssum

Rotation 3: something else!
-3 sisters (with sunflowers, or corn if I feel like dealing with corn)
-propagation bed for perennials
-Low effort self-seeding greens (arugula, claytonia)
-Annual herbs that may not play nice with everything else (like annual fennel)

Sweet and hot pepper guild (rotation 4):
Sweet and hot peppers
Pole beans, peas (trellis)
Green onions
Garlic
Radishes
Arugula
Basil
Cilantro, parsley
Sweet alyssum
Nasturtium

Melon guild (rotation 5):
Melons
Green onions
Pole beans, peas (trellis, sunflowers)
Sunflowers
Radishes
Nasturtiums
Marigolds
Sweet alyssum

Potato guild (rotation 6):
Potatoes
Pole beans, peas (trellis)
Radishes
Corn (if growing)
Lettuces, claytonia
Basil
Thyme
Sweet alyssum
Nasturtium

Perennials in various places across all of these beds:
Salvia
Chives
Walking onions, Welsh onions
Sea beets (if they can handle the summers)
Sea plantain (can give it a zone with sandier soil)
Salad burnet
French sorrel (edges, center aisles, around stepping stones)
Creeping thyme (same)

Outside of the beds, on the north side of this small yard, I plan to plant a couple beneficial ornamental trees/shrubs (they will shade the neighboring back yard), probably nannyberry and redbud, and around them I'll plant some herbs and flowers for insectary support, and maybe a couple of the more enthusiastsic herbs that I don't really want in the 4x8 beds.
