I like
Selah, but not particularly
Sela.
Sela just looks trendy and incomplete to me. I actually didn't realize til I just now looked them up that
Sela is in fact a name of it's own different from
Selah. I've only ever known of
Selah. I like the musical association, and it fits in with several other hebrew names that I like.
Selah Iris is lovely. Normally I would go for
Selah Frances, but I think it needs something a little more sweet and femmie sounding for a middle name.
I like these from your pnl:
