Explicit FTP over TLS. Which port to install?

Hi
My ISP has changed access to be secure and always encrypted.
They say I must use "Explicit FTP over TLS using Port 21"
I only need a client, I do not need to change my current FTP server at all.
Which port do I need to install to acheive this?
There seem to be lots to chose.
Currently on FreeBSD 11.1. Thanks in anticipation for your help.

Hi
I've now upgraded to 12.1
I'ver got some old scripts that login to servers and perform ftp transactions.
Can anybody tell me a simple to understand way to log into a TLS server?
I don't understand what filezilla is all about. I just want to use simple FTP.
