Classicist here. Sorry but AGORAE is absolutely not a standard plural for AGORA. It is a Greek noun of the first declension, so the plural has to be AGORAI. AGORAS is also common usage.

I'm sorry but Florence's roads were paved almost 2000 years after those of other Italian cities, such as Rome. Earliest known paved Roman road dates to about 525 BCE.
