Modern Effective C++ by Scott Meyers is my go to for people in this situation. I'm not sure if there's an even more recent edition that covers C++17 and C++20, but C++11/14 is definitely a great head start over C++03 and earlier.
The most amazing thing about it is how it manages to be so entertaining to read (the last thing I expected from a C++ textbook and a thing that made getting through it way easier)!

Sadly, there is not. Scott for-the-most-part retired in 2015: https://scottmeyers.blogspot.com/2015/12/good-to-go.html
