> But I'd love to know if there is a better list somewhere

There's a few lists but I suggest going through them and removing some entries.

Here's one list (tons of entries that don't make much sense): https://github.com/jedireza/reserved-subdomains/blob/master/...

This is another list which is a bit better quality: https://minhajuddin.com/2016/03/09/subdomains-to-restrict-fr...

Another list (there's some I don't agree with): https://github.com/nkkollaw/reserved-subdomains/blob/master/...

Thanks! I also found this list:

https://github.com/rbsec/dnscan/tree/master

Has entries for the most popular 100, 500, 1000, and 10,000 subdomains.
