I only left comments on the first two modules because the second two looked very similar. Just a few notes and some suggestions.

@EricPonvelle As my comment in the JIRA ticket,
For classic cluster, it uses the override image, the id can get from rosacli, here is an example to get them for 4.15 version, rosa list versions -o json|jq -r '[.[]|select(.raw_id | contains("4.15"))]'|jq -r '.[0].image_overrides.aws[]| "\(.region.id) \(.ami)"'
For hosted-cp cluster, it uses the same OCP image, It can get from openshift-install coreos print-stream-json and also embedded in OCP installer code https://github.com/openshift/installer/blob/master/data/data/coreos/rhcos.json , for different versions, we can get the AMIs IDs in the rhos.json in different branch, like "release-4.14".  
the versions for hosted-cp in document should only include versions >=4.14, as hosteed-cp commercially supports since 4.14.
Could you update the document accordingly?

@EricPonvelle what are the two separate AMI columns in the HCP section for? Is it that we have two separate AMIs for use? Different architectures?

[EricPonvelle]

@michaelryanmcneill when @iamkirkbater and I were running the commands, we found one set of commands produced two AMIs per region. I compared that to the AMIs he found, and they did not match. Then, using this idea, I tested the various openshift-install z-stream versions, and found that even within the same Y-stream, we had different AMIs per region.

The branch/enterprise-4.18 label has been added to this PR.

This is because your PR targets the main branch and is labeled for enterprise-4.17. And any PR going into main must also target the latest version branch (enterprise-4.18).

If the update in your PR does NOT apply to version 4.18 onward, please re-target this PR to go directly into the appropriate version branch or branches (enterprise-4.x) instead of main.
