Depending on what you're using for mulch will have more impact on sowing/planting than it being no dig. I have a 500 square metre no dig lotty, some beds are mulched with compost, others with wood chip. The compost beds can be sown direct, the chipped beds need to be drawn back to bare earth with a hoe before sowing into composted drills. Other than that plants are started off in modules. Regarding what plants to grow, do everything you always have, it might take a season for the soil structure to establish in a new no dig bed but I've never had parsnips, leeks and carrots pull out of the ground so easily.
