Narutopeidia uses one. With it, they don't need any more categories for characters besides just "Characters", but you can still filter them by each property. Clicking the icon in the infobox takes you to a page like this one, and if you hit the little plus near each property you get a list of characters who also have it, like so.

The thing is, our wiki doesn't have too much content and is generally easy to navigate even without the many categories. We have the navigation templates, portals that classify characters by their factions, the Teigu page contains users for each Teigu etc. Gender isn't even that important, just like the deceased status (and it's going to be almost everyone soon).
