Description
https://en.cppreference.com/w/cpp as the definitive reference to every version of the standard including future drafts (i.e. already listing C++23 features the committee is working on)
https://en.cppreference.com/w/cpp/links for links to the actual standards in free formats officially released (since the "published" version of the same pdf is hundreds of dollars, the committee releases the "final draft" which is the same content without the copyright restrictions added when it is published- it's silly, but that's IP laws for you). It won't be helpful to new people still learning what an if-statement is, but can be useful for learning how the standard writes code and adopting a compatible interface design so that your code is more compatible with code following standard guidelines.
https://godbolt.org/ as the convenient way to translate code into instructions to better understand what your code is doing with numerous compiler builds including the latest trunks (and some custom forks used for testing new features being considered for the standard)
These are all good resources

Up to you if you want to add any of these, but I do think cppreference.com should be the goto C++ reference in any guide.
Nice list, though. Oh, VS Code is a nice option now as an alternative to Visual Studio; runs much faster for large code bases, still uses intellisense, but with fewer advanced IDE features by default.
