Anything C++ 17 and above is golden. I personally use a few things from C++20/23 and rely a lot on carefully reading and trying to understand https://en.cppreference.com/w/ https://en.cppreference.com/w/ when it comes to anything I might not be familiar about. You dont have to use every single feature. Use whatever is required and if the need ever comes, go in depth with the language. Its about to become way more complex and cooler after c++26 and 29 [with possible introduction of contracts and reflection!]. There is no way to completely learn this language anymore. I am not even gonna try.
