The only genuine rhyme here is fiancé /fiˈɒnseɪ/, the masculine form, which sounds exactly like fiancée. Soirée /ˈswɑːreɪ/, née /neɪ/, café /ˈkæfeɪ/, and résumé /ˈrezəmeɪ/ share an accented é/ée spelling and end with a /eɪ/ sound, but they do not rhyme with fiancée because the sounds after the stressed syllable are different. Beware finance /ˈfaɪnæns/: it looks similar at the start but is pronounced very differently.
