Sibling name for luca

Caitlin • 1st born May 2017, 2nd born May 2020, 3rd due May 2024 💗

We find out the sex of our second in a couple weeks. I like shorter names (about 4 letters). And I like unique names but not too wild. I stumbled across Cruz recently for a boy and thought it was kinda cool. My husband shot it down 😖 any suggestions for a sibling that sounds good with brother Luca??
