In C++ you do it the other way around, have a single class that is polymorphic over templates. The name of this technique within C++ is type-erasure (that term means something else outside of C++). Examples of type erasure in C++ are classes like std::function and std::any, and normally you need to implement the type erasure manually, but there are some library that can automate it to a degree, such as [1], but it's fairly clumsy.
