Generator advice

I'm stuck when it comes to getting a generator as backup for our house. We live in a State that will not be favored in the next four years, and that will more likely than not lose power more regularly and for longer. I would love to maintain a standard refrigerator, a mini freezer, and have enough spare power to rotate between small applications (heating pad, instant pot, etc). I'm looking for recommendations on generators that would cover this without going over board, maybe a couple that would be overboard in case future winters get really bleek, and what I need to do to prep to install and use it (do I need an electrician to visit? Would the generator need to be kept inside? Etc)

Thank you in advance for this, and thank you for all your other prepping advice! Love you all for keeping me from spiralling out!
