If you aren't then https://deployer.org/ is pretty easy for beginners
For ECS, this is a CloudFormation template that might help get you started.
I'd go with AWS CDK & https://bref.sh/ for infrastructure and Github Actions for CI/CD stuff. I don't have much experience with CodePipelines, Github Actions are just so powerfull & simple. CDK is the best thing that has ever happened to AWS. DynamoDB for cache & sessions and AWS Aurora MariaDB for relational db stuff.
