If you want the broken POSIX behavior you can say 'setopt nonomatch'.

This makes quite a big difference indeed. Have you considered just not
unsetting caseglob?
Also of note (maybe) (without unsetting caseglob obviously) (and
setting extendedglob),
% echo $PWD/(#i)a*
/tmp/inaccessible/a/A /tmp/inaccessible/a/a
% echo (#i)$PWD/a*
zsh: no matches found: (#i)/tmp/inaccessible/a/a*

Eg, as long as you don't ask for case insensitiveness for the
unreadable segments, you're fine.
