Joining the array to form a string should avoid the need for a print,
allowing the #-o to apply to the string as a whole. E.g:

typearg=${${(j. .):-'-o -type '${^types:#-t}}#-o }

Shorter versions should be possible such as the following:

typearg="${${=types//-t/-o -type}[2,-1]}"

I'd be inclined to keep typearg as an array, however.
