How do we look up more verbose information by RequestID's thrown in AWS CloudFormation events which status reports CREATE_FAILED?

Without setting up a CloudTrail and executing a CFN template which rolls back, I have started looking at Debugging options. I found this which says we can see the most recent without a created trail.

I tried to find RequestId documentation from here entering 'requested' in the search bar, which returned many unrelated items to my specific case (thanks for the attempt Kendra:).

I also have looked at cli docs here

I guess I fist need to know what a RequestID is capable of helping me trace, as I am doing a simple debug of an instance I already know that has the wrong AMI ID for that region, but am trying. to re-familiarize myself. with fixing CFN templates after being out of the loop for a few years.

I'd like to know how someone else handles a CREATE _FAILED and ways to use the status reason in a verbose way. Each reason appears to be ';' separated, so even just a point in that direction might help weed through the mountain of information here. Thanks ahead of time- Rudy
