dynamic web application template (+1)

Looking to build a 3 tier application web application (not serverless) for lab purpose. I plan to leverage services in the following order: User > Route53 > ALB > EC2 > RDS, will integrate S3 in the architecture as well. I tied to boring default template I can use out of the box with wordpress. So I was wondering if you may point to a not so boring web app i can use in my architecture. For example, ride, dental or any other interesting template I can use.

Thanks in advance :-)
