But highly doubt you need anything like async/await for this kind of application. In fact, I'd go as far as to say async/await is almost never needed except for building networked services with truly massive performance demands.

If you genuinely have massive performance demands, stay far away from coroutines. For whatever reason the approach C++ took makes them incredibly memory hungry and inefficient.
