There's 20 and 21, but it's also using ports up in the teen thousands and 20 thousands. I'm trying to block all ports that I don't use, and it likes to just pick random ports up there. Is there any way to make it only use ports under 1,000, like a non-standard port number?

If you are using FTP passive mode, which is the default, Fetch will make outbound connections to port 21 and to the data ports chosen by the FTP server. Those are usually in the range 49152 through 65535. There isn't any way to tell an FTP server what ports to use.
I don't think you gain much security by blocking outbound ports, so this is not something I would worry much about.
