I mean, the three sisters works wonderfully as long as you’re not trying to harvest mechanically or minmax your yields. It’s a great way to produce food for a family or small village with a comparatively small amount of land and effort.
It’s common in backyard and community gardens for a reason. To my understanding: (1) corn is a fast growing, relatively high yield calorie and carbohydrate source and provides a natural trellis for (2) beans which stabilize the stalks and provide a protein and vitamin source, while (3) squash serves as a ground cover to retain moisture, limit weed growth, and produces fruit high in fiber and vitamin C.
The beans do fix nitrogen but this only plays a role in replanting for the next season, reducing or eliminating the need to fallow.

Somethin to keep in mind is that it’s a labor intensive harvest and the products aren’t really what we’d want to market. You’d wait until the whole lot of them kind of dies down and harvest winter squash, dry beans, and flint corn then till the remainder back into the soil.
It’s not bad for substinence farming, but you’re not going to get the yields or reasonable market prices with those crops.
