I haven't used C++ very much, but I found "A Tour of C++" to be a great introduction. It focuses on the core of C++ OOP semantics and is written by Bjarne Stroustrup himself. I like the book because it doesn't try to answer the question "which feature is the canonical way to solve problem X", since from what I understand, the "canonical" way to solve a problem in C++ changes quite frequently as new features are added. It was recommended to me by one of my professors a few years back for being short and accessible to a person who is looking to learn what makes C++ special, not how to program from scratch. EDIT: Reading the page again, it looks like the book does have some discussion of C++17 and C++20 features, but I focused on the first few chapters which really nail down the whole copy and move semantics feature as well as operator overloading.
