Thrust (in newtons or lbf) is a meaningful yardstick, but for a jet (or turbofan) it's measured in a static test stand, and that means little at cruise.
Further, thrust for a prop-driven plane isn't easy to find in print, but a rough rule is that static thrust (in lbf) might be 2.5 or 3 times the shaft HP.
I'm open to any refinements others might suggest.
