The "supervised" part is more legal than technical.
It can drive anywhere a human can.
Of course the goal posts can always be moved so the current real FSD isn't actually "Full" because of some inevitable imperfection.

No, it can't drive "anywhere a human can".
Based on videos I've seen, FSD is absolutely fine with unpaved roads. My guess is it would fare as well as your average foreign tourist when placed in Delhi or Nairobi. But we can only guess.
As for driving on "lightly flooded" roads, this is an extremely foolhardy thing to do, especially in a normal passenger car, and if FSD refused to drive in that circumstance it would not be a mark against its abilities. Arguably a mark in its favour. Moving water can be orders of magnitude more dangerous than it appears. Even shallow standing water can conceal debris which could insta-destroy a tyre, or your suspension, or your coolant loop, or your fuel tank.
