AWS has good base building blocks (ALB, EC2, Fargate, RDS, IAM etc). But it takes knowledge to put the pieces together. Thus AWS tries to create services/tools that orchestrate the base blocks (Amplify, Beanstalk) for you, which in my experience always becomes a mess where you don't actually understand what you are running in your cloud setup.
I'd recommend either learning the basic building blocks (these skills also transfers well to other clouds and self hosting) or using a higher level service provider than AWS (Vercel etc) - they do it better than AWS.
