I'm looking for detailed information about what the daemon facility would log if configured in /etc/rsyslog.conf.

So far, the most detail I have found is: daemon: affects a daemon without any special classification (DNS, NTP, etc.) (https://debian-handbook.info/browse/squeeze/sect.syslog.html)

Does anyone have a more detailed explanation of this?

Rsyslog is more advanced version of the grand old syslog. The facility code denotes which system is logging the message.

Facility codes are specified in RFC 5424:

          Numerical             Facility

              0             kernel messages
              1             user-level messages
              2             mail system
              3             system daemons
              4             security/authorization messages
              5             messages generated internally by syslogd
              6             line printer subsystem
              7             network news subsystem
              8             UUCP subsystem
              9             clock daemon
             10             security/authorization messages
             11             FTP daemon
             12             NTP subsystem
             13             log audit
             14             log alert
             15             clock daemon (note 2)
             16             local use 0  (local0)
             17             local use 1  (local1)
             18             local use 2  (local2)
             19             local use 3  (local3)
             20             local use 4  (local4)
             21             local use 5  (local5)
             22             local use 6  (local6)
             23             local use 7  (local7)

Not all facilities are available in all implementations.

daemon is a catch-all, it facilitates logging for otherwise unspecified sources. For example it would be used to facilitate handling syslog messages from an application you wrote yourself.
