I heard on Gardeners Question time that one should dig as little as
possible.
They were against winter digging.
But I notice that farmers plough deep.
What are the considerations?

Digging destroys the soil fabric, you should avoid touching established
beds, mulch and light weed only. Farmers do it to clear the ground and
because their crops are annual in which case it does not make as much
difference although they still have to fertilizer more than if they left
the ground alone, some american farmers started not ploughing to avoid
soil erosion problems, they use glysophate weedkillers to clear the
ground and discovered they got higher yields than when they ploughed as
the soil structure was better and held more water and nutrient. As
excuses go it is about the best you will find for taking it easy :~)
