It doesn't really tell you that, not yet. You didn't wait long enough for chronyd to decide.

All your output here shows is that all the servers are equally reachable since you started chronyd (very recently, except the NIST server) and the Facebook server had the most similar time to what is on your system.

For the aaplimg service, you'd be better off using the general hostname than a specific server that appears to be on a different continent than you.

So I just reran and here are the numbers. Outside of my local NTP servers, time.facebook.com still seems to be good.

I do use the generic time.apple.com entry along with other "official" names in my chrony.conf. I think my use of ODoH may be the reason why I'm getting systems further than expected. Will have to dig into it a little further.
