So... other than using std::function and other than something in Qt, what would be a more efficient C++[11,17] native way of doing a callback?

Going from "more efficient" to "most". That would be the assembly `asm("JMP *%eax")` instruction or something like it.

That would be the assembly way of doing a callback, not a C++ way.
