There should be data available for #1 -- it's not something we should need much subjective discussion around.
Re #2: I love all the other stuff. I never use EC2. Lambda, Cognito, DynamoDB, S3, CloudFront, Route 53, and API Gateway are my default stack, managed by Cloudformation. Granted, I'm doing smaller projects, but the costs are minimal, the setup time is trivial, the documentation is excellent, everything is nicely compartmentalized and 'just works' together. And I only pay for the actual traffic to the site.
