Personally I would LOVE to have that variety of wildlife in my yard! As others have pointed out, critters like opossums are very beneficial, and the others you mentioned pose no threat, unless you had chickens etc. Even foxes are not considered potentially dangerous to anything but the very smallest dogs.
As for the foxes: According to every resource I can find, they only occupy dens when caring for their young. Everything I found states that the family will abandon the den by late summer/early fall at the latest.
It’s your call of course, but I would be sitting there with multiple cameras enjoying and recording the show!
