Baby #3

Thinking of possible Baby #3 names.

My first Is Grace and my second is Zoey.

For a boy we like Otto. For a girl we like Fiona.

We also like for a girl, Olivia, Sophie, Mia and Kate. I can't use Kate because it too close to my SIL name. I'm worried that Sophie is too close to Zoey in sound. I would pick Olivia but I don't want to have 2 O names if we ever have a boy. Mia is still a top contender.

What do you think of Otto and Fiona? Are they too out there ?

Added- is it weird that Fiona is 3 syllables and Grace, Zoey and Otto are all 1-2 syllables? I'm probably overthinking
