Good morning and welcome o the site from SW Idaho.
Record the PDI for future reference, information overload could cause you to forget a thing or two.
Test everything, even the furnace @110 degrees, one thing this will do is burn off some of the oil on the furnace metal, it may set off the smoke alarm.
Put a cup of water in the microwave to test it.
Light the oven and burners, make sure the water heater is full and heating water.
Have them show you where the water heater bypass valves are even if you do not need to winterize due to your location.
