Oh, one project that I learned a lot of modern C++ from was, https://github.com/boostorg/spirit, I wanted to build a faster org-mode parser. I built at best a working prototype, but ended up learning a lot about how templates. It is also a header only library. If you want to avoid some administrative work, linking, choosing a build system, .... I figured it might be helpful.
