Use the long option name.  All of the options listed in ssh_config(5)
are available this way.

             Specifies which address family to use when connecting.  Valid
             arguments are "any", "inet" (Use IPv4 only) or "inet6" (Use IPv6

For IPv4 only you would use:

  sftp -oAddressFamily=inet
