Depends on the ISP and the teams doing the install. I used to work middle mile fiber along roadways from town to town and every bit of that was spliced on-site. There were very few exceptions where we would spec a pre-term cable for cell towers and certain buildings but we would often be splicing inside a building.

I suspect middle-mile has more trusted crews, this was literally "last hundred feet" or so. He did say he had pretty long pre-termed.

When they deploy FttH here in the Netherlands, it seems that the first crew just puts unterminated fiber under the sidewalk tiles, and then you make an appointment for someone to come along and splice it into your utility closet.
