Ooh, Gio is such a cute short name! Personally, I love pairing it with something classic like Gio Gabriel or Gio Miguel, feels balanced and not too long, no? A few of us moms in the group actually went through this, and one swears by checking kung paano tumutunog together, like how you'd call it out sa bahay, haha. Gio Rafael, Gio Marcus, or kahit Gio Adrian ay maganda rin, it really depends kung gusto mo mas traditional o modern vibes!
