Daikon do! Some varieties of radish go from seed to “ready to harvest” in as little as 3 weeks. They’re also great for nutrient cycling and breaking up dense soils in preparation for other plantings, Daikon does a particularly good job as they grow deeper than many varieties. Even when planted around other things they grow low to the ground so they rarely directly compete for light.

I normally plant at least 2 waves of radishes in my garden to start and end the season.
