Baby boy names!

Hi! I am 19w + 1d. My husband and I have been set on one name for our baby boy since before he was even conceived! I’m not sure if I’m having second thoughts or just being more willing to explore other names, but which of these names do you like the best? One of these names is our original pick, but I don’t want to say which one yet! Theodore (Theo), Jack, and Luca. Let me know what you think!
