Use anything except Celery, is my vote. Even if that "anything" is something you roll yourself.
Celery is mature, but has bitten me more than anything else.
For scheduling, there are many libraries, but it's good to keep this separate from Celery IMO.
For background tasks, I think rolling your own solution (using a communication channel and method tailored to your needs) is the way to go. I really do at this point.
It definitive is not using async, I think that will bite you and not be worth the effort.
