I can offer you one data point (i.e. I looked at one switch). It was
a momentary pushbutton and the contact bounce lasted around a millisecond.
The duration was relatively constant across activations.

There was no dominant frequency, it was very noisy. Since then I've tended
to allow 10ms or more debounce time and never had a problem with any switches
but there are bound to be some that differ substantially.
