re: States that border each other that you don’t view as border states

Point Roberts is another good one. It is completely isolated from the U.S. because it should be part of Canada, but fell below the 49th parallel. To drive to the U.S., you have to drive cross a Canada checkpoint, then back through a border crossing into the U.S.. They were kind of screwed during the CoVID lockdown. Canada wouldn't let them in.
