One thing that could be a niche content for your docs would be sample stacks for common tasks, because often it is hard to see how to put together the offerings to see what it takes to solve a problem. Sort of best-practices stacks and be able to price them. Lately I have been working on Grafana and showing how to create a VM with ingress, storage, apps, auth, monitoring - everything needed, and be able to see how to price it on different vendors. Educationally would be so helpful to see what production-ready stacks would actually be composed of and how to price it.
