Concur with all above - it will teach you how to fly. For a first job, however, knowledge of and experience on a C210 would, on average, help to get a foot in the door at more operators.
Your instructor and flying school have a lot to answer for though - why did they not suggest you do a tailwheel endo as part of your CPL training counting towards the 70 hours dual? Have they said it now to fleece more $$ out of you?
