Given your options, I would say 30/30. It is rimmed, the performance in a Handi will exceed lever guns, the ammo is the least expensive and easiest to find.
Since you already have a "light rifle" in the 243, there is a 444 barrel reasonable in the classifieds, if I did not already have one I would go for that. You can use that to 200yards and more with no sweat, good all the way up to Elk and for bear, easy to reload, rimmed case.
