The simplest answer is "don't bother". Switch to FTPS, which is
supported with quite simple tools like vsftpd and is vastly simpler to
entirely segregate user spaces for.

If you have a compelling need to support scp and/or rsync, you can
look at the old "rssh" tools, I used to publish RHEL wrappers for that
at , but stopped
maintaining my copy years ago. They're far more burdensome, and
maintaining the SFTP based "only see the upload or download folder"
configs is a lot more work, than simply using vsftpd and FTPS.
