Not a big city, but in Colombo, there is an ISP that exclusively provides Fibre lines to apartment buildings. It's a common interest for both building management and the ISP to provide service.

If the building signs up with the ISP, any customer from that building can sign up directly at ISP, and they can setup the connection within the same day.

Price wise, they are on par with other ISPs, but the Sri Lankan government heavily regulates the prices.

Yes, fiber is common in most Dutch cities for example. It is not at every premise yet, but being rolled out. If not FttH, then ~100Mbps DSL or Docsis up to 1000Mbit down.

South Florida here, I've had FTTH for 2 years now and gigabit cable has been an option for longer than that.

The last two places I lived in NYC did have fiber to the apartment, so it’s not NYC as a whole that doesn’t have it.
