C# specifies the language, not the runtime. Apart from .NET and Mono, you can compile C# to cpp (what Unity does under the hood, btw).

There are many instances where other programming paradigms are more usable - but in my experience, gameplay logic, specifically, maps very well onto classic OOP concepts.

If gameplay mapped well onto OOP then the big game companies would use it, and not data-driven programming (specifically, entity-component systems). I think that there are a couple things that require OOP-style dynamic dispatch, but they don't need to be pervasive, even a function pointer stored as a struct member is more than enough to provide all the benefits of OOP without having to take on all the drawbacks.
