You list some good use-cases for C++, but the other side of the coin is that there are languages out there nowadays that are better than C++ for a large majority of the use-cases where it fits best (Rust being the obvious example). Yes, there are surely still a few cases where C++ beats Rust on raw merit. And of course C++ still has the advantage in the number of developers who can competently contribute to your project in short order. But both of these advantages are diminishing rapidly, and—to me at least—the writing is on the wall for C++. Its days are numbered.
