Hello and welcome willybell :D Yes, spring cabbage is great for intercropping/catch cropping. I have intercropped spring cabbage with beetroot, lettuce, nasturtium and tomato - in the latter case, the tomatoes will take over the bed when you crop the spring cabbage. My Booke says that cabbage will also enjoy growing with carrot, celery, cucumber, dill, dwarf bean, kale, mint, the onion family, potato, rosemary, sage, spinach, and thyme.
Cabbages will enjoy growing with other cabbage family plants for different seasons, but you will a) need crop protection at times of year when they are vulnerable to pests if you grow them all together, and b) want to watch for soil-borne diseases - it would be a shame to lose them all if you have e.g. club root, so spreading your risk - and your crop - might be a better risk if you're at all unsure.
