The main reason I learned C++ a few years ago was because of my concerns with portability. At the time, it was not trivial to run C# code on consoles because C# was "just in time" compiled, which isn't something many platforms allow. Our game, Celeste, used a tool called BRUTE to transpile the C# IL (intermediate language binaries) to C++, and then recompiled that for the target platform. Unity has a very similar tool that does the same thing. This worked, but was not ideal for me. I wanted to be able to just compile our code for the target platform, and so learning C++ felt like the only real option.
