Is there any job/career that pays an average salary of around $50K a year and a shorter workweek?

Really only the owner of a mature self running business comes to mind, and getting to that point might take long hours and risk.

There may be very successful commission salesmen who make that on a small work week, but competitive forces from others and the temptation of more money may make it hard to keep those hours down.

More typically those low hour jobs are entry level low pay positions. <
