Restrict yourself to a set of simple, generic queue API, .e.g. put, getNext, getWithID. Abstract those APIs and implement with them with SQS first. It's fairly easy to switch to a another implementation (Kafka, activemq, etc.) later. Even in production, you can easily switch off the producers, drain the queue, move to the new queue, then restart.
