So, I might just be way off, but even in measure 7 I'd use a D flat instead of C sharp. It feels like a diatonic run in the violin with the D flat borrowed from the key of F minor to me (which is only one flat away from the key you're already in). I know the "rule" about using sharps going up and all, but that really just feels like a diatonic run to me. The B natural (raised 7th in C minor) helps keep you grounded by pulling very hard back to C minor. Also, the B natural is the raised 4th of F minor, and raised 4th is being used a lot when you're on the tonic as well which helps keep the feel. Very much double harmonic minor in feel all taken together. Your actual question... Honestly I don't know and feel the same as others you've asked. I guess the violin in measure 12 feels like it's hitting a flat 5, so personally I'd choose G flat throughout that section for consistency. But I dunno, it's kind of a toss up to me.
