I'm actually on the same train right now, are there any good learning resources to get into modern C++(CPP17/20)?

If you are starting with C++ right now, I'd suggest Scott Meyer's More Effective C++ (and his other books) and the books by Herb Sutter. Don't worry too much about C++ 17/20 unless you are working for a company that use the newer standards. A lot of companies still stick to C++ 11.
