Hey, I had a quick question. What is the reason for the port to be set to 'null' if it is equal to the URL scheme's default port?

https://url.spec.whatwg.org/#port-state

Set url’s port to null, if port is url’s scheme’s default port; otherwise to port.

Basically, because the canonical form of https://example.com:443/ is https://example.com/, not https://example.com:443/. This is most important when serializing, but maybe has some other impacts too.
