[name_u]Alvis[/name_u] means all wise (it’s traditionally masc but i feel like it could be neutral)
[name_u]Dana[/name_u] means wise in Persian
[name_u]Alden[/name_u] means old wise friend?
Some names that have similar sounds or letters…
[name_u]Shiloh[/name_u]
[name_u]Sasha[/name_u] (I think you considered this before though)
[name_m]Soren[/name_m]
[name_u]Ophir[/name_u]
[name_u]Solaris[/name_u]
[name_u]Sonnie[/name_u]
[name_u]Sorrel[/name_u]

Based on a similar sound, maybe [name_m]Sofiane[/name_m] or [name_f]Safa[/name_f]? [name_m]Sofiane[/name_m] is a (masculine) variant of [name_m]Sufyan[/name_m] but I would not be surprised if it has also been used as an elaboration of [name_f]Sofie[/name_f] / [name_f]Sofia[/name_f].
[name_f]Safa[/name_f] is unisex, but most common as a feminine name. It can mean “clarity” which could match Sofia’s meaning “wisdom” ?
[name_u]Cato[/name_u] means “wise” and is traditionally masculine, but the sound feels ambiguous to me (similar to [name_u]Caro[/name_u] and reminiscent of Catherine)
