You're correct about Q but only the one with a backslash seems to make
any difference to ${(e)...}:
% print -rl -- $quotings
"$HOME/foo/bar"
'$HOME/foo/bar'
$HOME/foo/bar
\$HOME/foo/bar
$'$HOME/foo/bar'
% print -rl -- ${(e)quotings}
"/Users/schaefer/foo/bar"
'/Users/schaefer/foo/bar'
/Users/schaefer/foo/bar
$HOME/foo/bar
$'/Users/schaefer/foo/bar'
%
Compare this, which is I'm sure what you were thinking of:
% eval print -rl -- $quotings
/Users/schaefer/foo/bar
$HOME/foo/bar
/Users/schaefer/foo/bar
$HOME/foo/bar
$HOME/foo/bar
%
