Did you even read the article ? He has given the recommended path in the article itself.

Two books describe C++ following these guidelines except when illustrating errors: “A tour of C++” for experienced programmers and “Programming: Principles and Practice using C++” for novices. Two more books explore aspects of the C++ Core Guidelines

J. Davidson and K. Gregory Beautiful C++: 30 Core Guidelines for Writing Clean, Safe, and Fast Code. 2021. ISBN 978-0137647842
