Ethan,
I'm an adult open heart surgery survivor so I won't address any of your child related surgery questions and will let others whose kids have undergone that procedure address those questions.
I do though want to make the point that, although bedside manner is nice, competence is paramount. As I expect you know based on your surgeon father, surgeons are technical specialists, like dentists, and the best ones possess not only exceptional judgment about dealing with emergencies and routine issues while a patient is under the knife, but also the hand/eye skills of a sculptor in performing the work.
Do yourself and your family a favor and chose the best technical surgeon you can find rather than worrying whether she or he is " a nice guy." If you can get both, then fine, but I wouldn't sweat it too much.
I met my thoracic surgeon once, for 2 minutes before my emergency open heart surgery and only saw his nurse assistant afterwards. I was fortunate that he was regarded by medical professionals as a top surgeon.
Now, with respect to your child's cardiologist, who your family will be seeing on a regular basis, bedside manner IS critically important and as important as technical knowledge and experience, but that's different than a surgeon who will be attending you while you're unconscious, under the knife and who you will not normally be seeing more than once or twice.
Good luck and good health to you, your wife and your child.
