I wouldn't rely on "setup everything in 1 command" as indicative of platform quality but .NET does come with the CLI and the unmatched Visual Studio, both of which have plenty of templates and tooling to get you started quickly.

Everything you mentioned can be done with some packages and a few lines of code, and the entire framework does have some opinionated conventions but with much more freedom than Rails. The fact that you can have MVC, Razor Pages, raw controllers, and Blazor all in the same app shows just how much freedom you have.
