We downsized to a new little townhouse a decade ago. Boring as hell, but the estate uses pavement ducting, then individual house ducting. I saw OR pulling the fibre up and got my FTTP order in a nanosecond after. Originally, the deal (BT) was Fibre 100 for the same price as we’d been paying for FTTC then abt a week later, they offered an upgrade to Fibre 900 for £1 pm more. Well, that was a tricky one 😂
From the house external box the fibre runs across the front outside then curves gently up, through the wall and into the ONT the other side. So right angle changes no good, but gentle curves should be OK. Certainly, ours is fine. I can now print from downstairs to the Epson upstairs, which I couldn’t w the BT router. A WiFi TV and assorted Alexas upstairs are fine too. For my main internet device, the EE app speedtests as this:
That side of things, I’m happy with.
TV/SIMs, not so much.
OR are pretty flexible where the ONT will go, particularly on the same side of the house as the telephone pole, & will fit in with your requirements as to its positioning as long as there's a spare power socket nearby.
From where they fit the external junction box they can run any length of cable to the point on the outside wall opposite to where the ONT is to be positioned, e.g.:
