I'm not sure I can help with the content of your speech, because I'm not very knowledgable in this area - but for what it's worth, your argument in writing is, I think, well thought-out and touches on many concerns that should be quite popular with a city council. Also because I think subletting of the air-bnb typically means less taxes for the town when compared with a hotel or similar, at least in some areas. Residents complaining as well, with reasons both personal and communal, probably strengthens their case against that (which they might have).
In short - I totally think you can do this! And I think being invited to council, if it's not standard procedure, could be a sign that they want to give your issue more visibility, so they can help you (and thus themselves) better! (And yes, in that case, being heavily pregnant is probably also a big advantage, indeed.)
