I have recently been hired at a retain search firm that is a startup, and the proposed title at the initial interview was "office manager." This feels like a huge step backward for me, and it also doesn't seem to encompass the scope of the job: human resources, accounting & financials, marketing, process development, and more. Do you have any suggestions for what else I could propose? My new boss is open to a different title, I just need to come up with some good ideas. Thank you!

Make full use of this. When you go looking for your next job - which maybe some time away - your title will matter. At the same time, don't get pushy with your new company.

The problem here I think is with the word "office". Try to change this to something else. You could try Manager, Growth or something else. I think going into jobs, a title that talks Business Development is more likely to be appreciated than others.
