I don't think it's selfish to want your family there when you die and not to be alone. I think that's normal, to be surrounded by your loved ones so you can say goodbye.
My dad stayed with my mom right up until the very end. He held her hand. He said the moment before she died she squeezed his hand, because at that point she couldn't talk. But, at least she knew she wasn't alone in her last moment, so I don't think it's selfish.
I don't have a bucket list. Personally. I used to have a lot of plans about dying but not any more. Currently my plan is to live as best I can. But, I understand how scary it is to need surgeries like that.

In July I had to have 3 surgeries in one week and was in the hospital for two weeks. It was really scary. But now I'm okay.
