My favorite way to connect to FTP servers on Linux was with lftp from the command line. I say was because I don’t really use FTP anymore. I do use Linux still though.

lftp is available in every package manager I know.

Man page: https://linux.die.net/man/1/lftp

Actually lftp supports a lot of different protocols but I only ever used it for FTP, FTPS and SFTP.
