As the other poster says, FTTPoD is more a bespoke business product.
If FTTP becomes available, then knowing about sockets and the like is not required.
The ONTE will be installed at an agreed location , from there an ethernet link can be made to the router, and then it pretty much just works ...
If this is the Openreach based product coming your way, then choice of ISP is rather small BT Retail, BT Business, Zen, Plusnet, Cerberus, FluidOne, and a few others, all BT Wholesale based.
I suspect it may come across as a faff to get put in, but then fairly painless.
There are other companies providing FTTP , but I have no experience of them.
