Excellent list! Add to that: Bottles of water (it doesn’t pay to get dehydrated esp if stranded. Can keep one or two inside your jacket to keep them from freezing.)
Hand warmer packets (I find changing a tire in icy weather drains/numbs my hands in short order, then I skin my knuckles etc easily.)
In our current location, a good rain jacket/poncho since cold wet rain is more hypothermia-producing than cold powder snow.
