I need to expand a glob pattern (like ../smth*/*, or /etc/cron*/) into a list of files, programmatically. What would be the best way to do it?

You don't need to do anything special, just don't quote the*.

Just let it expand inside an array declaration's right side:
list=(../smth*/) # grab the list
echo "$#list[@]" # print array length
echo "$list[@]" # print array elements
for file in "$list[@]"; do echo "$file"; done # loop over the array
Note that the shell option nullglob needs to be set.
It is not set by default.
It prevents an error in case the glob (or one of multiple globs) does not match any name.
Set it in bash with
shopt -s nullglob
or in zsh with
setopt nullglob

There is a problem. If pattern matches no files, it prints itself - which is not very good.
