Depends on how long you are away from home. It will obviously take the most energy to keep your house at a consistent temperature from the time between noon and 4pm. If you're not home during that time leaving the system off will make a huge difference.
If you want the temperature of your home to be at comfortable levels when you get home, then you should put the unit on an outlet timer that turns it on 30 minutes to an hour before you normally get home, and turns it off right before you normally leave.

Because it's heavily insulated and doesn't lose much over time as long as you leave the door closed.
A 20 degree difference in the exterior temperature of the fridge won't make a huge difference to the interval cycle because when it remains closed it only has to compensate a very small amount.
