Unique or Spanish boy names for middle name Alexander?

Shelby🍍
We really like Zachary Alexander but we want to keep our options open. We don't like classic names like Jeremy or Kevin and my husband will not do any Biblical names. I just don't want anything that sounds southern or unnecessarily masculine. And for the love of God, please no Brantley/Bentley/Brayden etc. I'm also always up for a Spanish name since I'm Mexican-American. We've literally gone through the top 1000 boy names from last year and still can't find anything we like so that list is out for us.
