Answer 1

If you install WebMatrix this will give you a list of some of the more popular ones.

I know this doesn't (exactly) answer your question but I think WebMatrix is a pretty good place to start and see which might best fit your needs.

Answer 2

I don't know if it's the most popular, but Umbraco is a good option that should cover most of the features you've mentioned. It's also ridiculously easy to extend with custom functionality using its API.

Asp.Net has recently switched to using Umbraco. I guess that should count for something.
