The better solution in my experience is to create an entirely different account to your production environments and just deploy things there to test. At least that way you're dealing with the real SQS, S3, etc, and if you have integration problems there, they're actually real things you need to fix for it to work in prod - not just weird bandaids to make it work with Localstack too.

Made me wish for a simple VPS, an ansible script to setup nginx and fail2ban and all that shit, and a deployment pipeline that scp'd a single binary into the right place.
