My all around choice would be a Beretta 390/391, Browning Gold, or other quality gas operated semi-automatic with 28" barrel as it would have the heft for a full course of sporting clays or heavy pheasant loads while being light enough for hiking all day after grouse. If grouse were the main course and the others only occasional then I might settle for something light like a Franchi 48 or Benelli Montefeltro and suffer through pheasant loads and sporting clays.
I got by with the former for years but have come to appreciate having guns better suited to the task at hand. One can get by pretty well with a jack of all trades but the rest of the saying is true too- it is a master of none.
