Stonyground that is a good plan to go no dig.
Without seeing your compost it’s hard to say. I expect that radish and turnips will do well but carrots will benefit from some finer compost, perhaps just to line the drill you draw.
All of these seeds, sow as shallow as possible. It’s a damp time of year so no worries about moisture, and they risk disappearing under lumps if sown deep.
