An application domain where C++ is notably better is when the ownership and lifetimes of objects are not knowable at compile-time, only being resolvable at runtime. High-performance database kernels are a canonical example of code where this tends to be common.

Beyond that, recent C++ versions have much more expressive metaprogramming capability. The ability to do extensive codegen and code verification within C++ at compile-time reduces lines of code and increases safety in a significant way.
