(G)PON, (gigabit) passive optical network, seems to be what everyone is moving to:

* https://en.wikipedia.org/wiki/GPON
Even for wireless (LTE/4G, 5G), GPON seems to be used for backhaul:

IEEE 802.3ca-2020 allows for 25 GigE per lambda, being able to combine two for 50 GigE; I'm sure there's an ITU equivalent (or will be soon).

The main 'semi-hold out' are cablecos, where they are pushing fibre closer and closer to the premises, but generally haven't yet decided to replace co-ax in people's homes yet:
