Rules for Predicting S or Z sound (besides 3rd person/plural endings)

Many sources have published the rules for pronouncing s or z at the end of a 3rd person singular or plural word.  Fewer sources have published other rules governing S and Z.  This is what I've come up with:

1)      The following letter combinations often make the “S” sound: ce, ci, cy, x, psy, consonant +se, cc +e, i or y, sc, ss and s
a.      Ce: Ice, rice, price, entrance, since, face, trace, peace, place, niece, procedure, necessary, police, office, license, cent, certain, receive, cell
