It is my understanding that the Generac standby generators can operate on natural gas or propane. Do you have to specify when buying one or does it come capable of using either? If so, other than switching the supply what has to be done internally on the generator to go from one to the other?

From Generac Q&A site about the 20kw....
Our home standby generators up to 45kw come set from the factory for natural gas but are easily field convertible to propane. To convert from natural gas to propane, and vice versa, you will want to reference the section in the owner’s manual titled “Reconfiguring the Fuel System.” This section of the manual will detail the steps to convert from natural gas to propane, and back, for each of our different models. It is not advised to continually perform this reconfiguration, but in the event of an emergency or a change in available fuel supply, it is a simple conversion. Local codes will dictate what is needed to adequately and safely supply the fuel required. Unfortunately we are unable to determine the proper way to install this type of set up for your particular application as we do not specialize in gas line installation. You will want to work with your local certified plumber to determine the best way to install the unit to meet your needs. It will consume approximately 2.9 gallons of propane per hour when operating at full load. The fuel consumption will decrease as the load decreases; the unit will consume approximately 1.89 gallons of propane per hour when operating at half load.

What size and style of the Generac are you considering? Key things to consider is actual load(s) you wish to power during a grid down event. You may also be able to get away with a smaller unit and save dollars if you purchase the load shedding modules.
Can't go wrong with NG if its already piped to your home. Would love to see another generator install thread if you ever commit to buy and move forward.
You may consider going with a liquid cooled unit for more money but longer service life as they run at a much lower RPM.
