If all you are doing is watering you probably don't need a tank if you design the irrigation system properly.
Do a test to determine how many GPM the well can deliver for an hour without pumping it dry.
Then get a shallow well jet pump that is compatible with the capacity of your well, and that will deliver the GPM you want at 40 to 50 psi. You may be looking at a 1 HP pump.
If you hook up your irrigation system so it is never completely valved off then you can run it with a manual switch. You can set up a contactor (relay) and use a transformer and low voltage circuit for control if that is most convenient.
Lay out your hoses and sprinklers and turn on the switch. Don't use the pressure switch.
The pump will operate at a pressure that will allow the sprinklers to deliver water consistent with the characteristics of the pump.
A shallow well jet pump has a shutoff head (pressure) that is in the safe range and the pressure will not exceed that pressure.
In a setup like that the pump will never cycle on and off during the run and it won't hurt the pump as long as there is at least one hose open.
When you want to move the hoses to a new location, turn off the pump, move them, and turn on the pump.
