What is your Wal-Mart factor? Do you have to be able to walk into a LGS and get the cartridges off of the shelf, or can you reload?
As far as pistol cartridges, I suspect the shortness of the shell is going to be the limiting factor for you, not the caliber. My Dad has a similiar issue, and the longer rifle shell cases help him a bit.
The 30-30 is the only one on your list that I know of to have "managed-recoil" loads for it, Remington and Hornady both provide an option. Might be the solution for slight/younger shooters.
