It shines at creating highly concurrent applications with a great deal of built in features to provide reliability and resilience. Sounds a lot like a server, and that's what much of the modern use for Elixir is. In particular, one area where it shines is stateful, long-lived requests (e.g, websockets) where many other concurrency models will either rely much more on databases to track state or potentially get choked up.

If nothing else it's neat to learn as one of the few somewhat well used languages in modern times that actually adheres to Alan Kay's original conception of OOP.
