The SR22 is a fun gun to shoot...
But I would add the Ruger Mark III or 22/45 (based on the Mark III) to your list. They are very accurate pistols and are easy to shoot well and accurately. That is very important when learning to shoot. You will see an improvement as you improve, and you will know that any inaccuracy is you not the pistol.
Being easy to shoot and accurate can help sway those not very fond of firearms.
The SR22 is decently accurate for a short barrel 22, but even when fired from a rest it has groups of a couple inches with good ammo.
The Mark III and 22/45 can be had for about $275-350 on the cheap end with adjustable sights.
