Speedguide has no authority and I for one had never heard of it. IANA is the source.
IF we were to consider an alternative port then it should be advertised by means of a DNS SRV record. But that does not seem necessary.

This was intentional and keeps the port numbers within the standard set of 'authorized' ports (in the notion of unix systems) - ports <1024 requiring privileged access.
This is generally true (but not explicitly) on other systems.
Given that WoSign/WoTrus's past issuance systems allowed unprivileged users to obtain certificates through the use of high port numbers (in this case, for STUN/TURN services and SSH), I do not think it particularly wise or encouraging to consider this.

Forwarding from Richard Wang:
The current BRs say:
Authorized Ports: One of the following ports: 80 (http), 443 (http), 25 (smtp), 22 (ssh).
But many internal networks use the port 8443, broadly used in Apache server, today, one of our customers uses this port and can't change to use another port, I wish you can help to add this port 8443 to be allowed in the BRs, thanks.
https://www.speedguide.net/port.php?port=8443, it says "8443 is the Common alternative HTTPS port."
