Hi, for me visitors belongs to customer, and employee belongs to private.
I think between designated and official there are different opinions. For now I would say there is no big difference. Both used primary for foot-, cycle- or bridleways.
A way with a sign: "Private way, use with own risk" I would tag with access=permissive. And maybe i.e. a only footway-bridge (foot=designated), which connecting 2 big cycleways/-routes, I sometimes add bicycle=permissive. (Second example is my personal view. Maybe bicycle=unmount is also possible.)
