30 years of flying both large Part 121 and small GA aircraft, I would go with a 2011 or newer SR22 (NA). (Don't buy the turbo). I operated 3 of them over the years and they are great planes. The G1000 and G700 Autopilot make the plane easy and a pleasure to fly. I think your chances with the CAPS system is better than your chances of losing an engine in a light twin and trying to fly with the operating one. Not to mention if anything ever happened to you, your family would have a very good chance of walking away if they are well trained on how to handle a CAPs deployment.
Feel free to PM me if you want any more info.
