I don't know what the Q service is, but Sky fibre broadband is using Openreach GEA. Whether you can get FTTC or FTTP is a binary choice/decision made by Openreach at the time they enable your cabinet.
There is currently no upgrade path between the two. That will only come years in the future when all the copper lines get scrapped. If you are on FTTC with anyone then that's the best you can have.
There is what is called FTTPoD, (oD = on Demand), available from a few suppliers, but it is hideously expensive at well over £700 installation cost (up to several thousand depending on distance from an aggregation point) and subject to feasibility survey. Not only that, but I believe Openreach have "temporarily" suspended sales while they try to find a better alternative.
AIUI Sky do not do the normal FTTP anyway. Their FTTC Pro is in effect a mirror of Infinity 2, just different freebies.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
