Erasmus (depending on how you pronounce it) or Rasmus, which is the Germanic version & a common name in Sweden, Denmark, etc.
Wednesday. I think. I've said it out loud a few times, it sounds to me like there is a "z" sound in there, but it's not as obvious as in your examples.
Some names that end in -iah, like Josiah, Isaiah... there may be others, those are all come to mind right away. Boaz has it at the end. Moses/Mosiah.
Is Desi pronounced like a "Z"? Alexander/Alexandria. Josie. Pansy. Susan/Susanna. Amzi (male, pronounced em-zi). Isidore. Casimir.
Some of these names are borderline... you can say them with a soft or hard "s," so I'm not sure if they fit the bill.
