Better default NTP config for Amazon software that usually runs inside AWS but sometimes runs outside? Amazon Corretto, Amazon Linux, etc?

This helps Amazon claim that those "run best on AWS", as NTP would be in the same datacenter (I think?) otherwise it looks like they use a regional endpoint[1].

Being slightly closer to a NTP server doesn’t at all warrant saying a service runs best on AWS. Accurate time isn’t going to improve your Linux or Java performance in any way.

Accurate time is critical for ensuring Data accuracy and most apps utilize the system time. There are also a lot of Database functions that require accurate time. If you want to do DB clustering then a good reference time is required and Oracle even went so far as to make a service called "Cluster Time Synchronization Service (CTSS)" that specifically validates the system time configuration. Although why they still only support ntp and not chrony is something I would love to know.
