Is multi-step (fan out, etc) typically something a queue or message bus would handle?

I’ve always handled this with an orchestrator solution like (think Airflow and similar).

Or is this a matter of use case? Like for a real-time scenario where you need a series of things to happen (user registration, etc) maybe a queue handling this makes sense? Whereas with longer running tasks (ETL pipelines, etc) the orchestrator is beneficial?
