When I was a kid, we used to play for funerals, our teacher asked the parish priest what was correct to play, unfortunately, it's been more than 55 years and I don't remember the titles (especially since they were mostly in Latin).Times have changed since then, go see a priest, he won't necessarily advise you to play church pieces (if that's the case, you'll go see a younger one).Good research.SincerelyDaniel
