From my early years I saw my Father rotate, and I did too when I got my own Gardens. It is over four beds size does not matter 1) Legumes and pods, 2)Alliums (onions) and leeks, 3) Root crops and tubers, 4) Brassicas (all the cabbage family) Kale swedes radishes etc. Each year move one block clockwise. Legumes roots feed Nitrogen into the ground which is why Brassicas move into that bed. It has its faults, four years is not enough to get rid of club root and the way to deal with that is to grow brassicas in pots then transfer the whole pot to the plot setting in a larger hole with some good compost.
These days I grow my Beans and Peas in large containers for ease plus the Grandchildren find them easy to pick and eat fresh. with an allotment rotation would be necessary but small gardens it could be done moving different types into containers of fresh soil. You toss the coin and take your pick, there are no wrong ways in gardening.
