Authoritative resources or sites for modern c++?

Hi! Im wondering if theres any resources that would give us modern approach to the language. Things like std::print has implicit format (correct me if im wrong), which I didnt know till i asked ai (wrong approach) why use that over cout. Im a beginner and wanted know the “modern way” for the lack of better term. Thanks!
