Ziggy and [name_u]Cam[/name_u] are both cute in super different ways. I like [name_u]Casey[/name_u] a lot too, but I haven’t ever considered [name_u]Stacy[/name_u] for a boy so that will have to grow on me lol
Iggy is a slightly more mainstream version and can be short for [name_m]Igor[/name_m], [name_m]Ignatius[/name_m] or just be [name_m]Iggy[/name_m].
There is also [name_f]Ibby[/name_f] for [name_m]Ibrahim[/name_m], and he could also go by [name_m]Bram[/name_m] which I think is a super cute choice that might be up your ally.
I thought [name_u]Dash[/name_u] was a good suggestion.
My other suggestions:
Sidney “[name_u]Sid[/name_u]” (I love this one, I think [name_u]Sid[/name_u] is so cute and [name_u]Sidney[/name_u] is too and seems your taste!)

[name_m]Zev[/name_m]
