Generator for whole house

So I’m looking to go buy a generator tomorrow since we are going to get hit with a decent storm. My house is 1625 sq. Ft. I would like to be able to power the refrigerator, well pump, furnace, lights and TVs if possible( maybe my PC too so I can get some gaming in lol). I would get a smaller generator but I have 3 under 4 so I would like the convenience of having most of the house good to go so it all goes smoothly.

I was thinking of getting the Predator 13000 tri-fuel. If anybody has any other recommendations I would greatly appreciate it since I’m not well versed in this area. Thank you.

Edit: Heat is fueled by propane but I would be using gas for the generator in this situation because I don’t have a feed coming from the tank.

Edit 2: I have a transfer switch with an outlet for the generator next to the breaker panel.
