AzCopy would probably be a good fit for your use-case. If FTP is not a hard requirement you can download the blob or file directly on the destination server. If you need to first download then transfer with FTP, you can download the blob locally then use the required FTP command to transfer the file. I do recommend using the SFTP as FTP is unsecure.
Hope this helps. Let me know if you have further questions or issues and I will be happy to assist.
