How much of an average commercial flight on a large airline and
aircraft today is done automatically,

I used to routinely hand fly to 20-25K on departure, and from 10K down on
arrival, just for the enjoyment of it. There were some exceptions, such as
an approach in serious weather, or at the end of a ten hour flight, when
everyone is already tired. Better to let the machine do it, and just
monitor.
