RabbitMQ. It's so cheap and easy to startup a super performant queuing broker with docker these days. And the libraries are all there, async ready and with established patterns. Closest to zero code you can get for this. You'll likely end up reimplementing all those patterns and support around them using redis.

If you want something quick and easy and dirty, go with Redis. But switch to Rabbit when you start having to write a lot of handling and other code.
