First Home Winterizing

Purchased my first home in Iowa this summer! She’s a beautiful 1915 craftsman who has been pretty well taken care of but does need some love here and there.
With this being my first home, and a century home at that, looking for advice on what I should do to protect the house, and us inside, from the impending winter.
Currently, I’m planning to replace a couple missing shingles on the front porch and shore up the garage which has some termite damage (no active termites thankfully!). What else should I make sure to do before the temp drops?
Thanks all for the guidance!!
