AWS Proxy Architecture with Global Accelerator, ALB, WAF, etc.

Have you got a proxy server or reverse proxy server that you want to make available to your users with the help of AWS services? Or do you want to use AWS services to implement a reverse proxy layer in front of your internet-facing applications with AWS mechanisms?

For the latter, CloudFront protected with WAFv2 (and optionally Shield Advanced for advanced DDoS protection) would be the most powerful way to provide users worldwide with entry points into AWS's network when accessing your service. In the region or regions where you run your application, ALB would act as a gateway between CloudFront and the compute platform of your application in your VPC.

I think we can find some blog posts with details around the CloudFront+WAF+ALB frontend acting as a reverse proxy and caching layer, if that might be along the lines of what you were looking for.
