Has any one ever changed the oxygen sensors in a late '90s Crown Vic?? The upstream sensors and their wiring connectors seem pretty much inaccessible…

There are a multitude of different specialty wrenches for O2 sensors. I imagine one of them should work in your application.

here are some examples:

You could probably find them cheaper somewhere else though. Or do what I did and make a friend at a muffler shop and borrow his. Even with the proper tool, sometimes the awkward angle can make the removal a real chore if those puppies are in there tight. In my case, I wound up wedging my foot up in there on the wrench handle and used my leg to get it going.
