A related very useful keybind is
bindkey "^N"      _most_recent_file
although it completes files and directories alike, despite the name.
Also very useful is
  bindkey "^[^N"    _most_accessed_file
Just copy _most_recent_file and apply

<   eval "file=($PREFIX*$SUFFIX(om[${NUMERIC:-1}]N))"

PS why the ls invocations? this seems to work just as well
alias -g NF='*(.om[1])'
alias -g ND='*(/om[1])'
