For talking to other AWS services you can provide it with an AWS profile to use (see the --profile option on sam invoke local and sam local start-api) and it will then use those services in your AWS account.
It is possible, but somewhat more complicated to run test versions of DynamoDB and mock versions of some services in Docker (see the localstack project) - but requires you to run the services in the same docker network and override the endpoint that is used to communicate with the services.
If you're just consuming messages from SQS, the sam local generate-event command can be used to create test events to feed to sam local invoke.
