Thinking about replacing an old porch this summer. Central Wisconsin.

What is recommended depth for footings of corner posts?

Around here the building inspector has taken a liking to the
earth screw ground anchor. Screw down below frost line. I used them
for my decks a few years ago. No movement at all.

The anchors I used had a threaded end and a adjustable bracket for
bolting to the wood.

They're called ground hogs around here. Home Depot has them.
