Switching to Community Fibre; internal cabling question

[Otorongo]

I'm currently with VM and have a coaxial cable concealed under the floor all the way from the front to the rear of the house where I need it to be. I'm switching to CF, where I can't simply re-use the coaxial. I made a post about it a few months ago.

However, I've now remembered I also have a concealed Ethernet cable running through the lounge where I want it concealed. Not sure what type (Cat5, Cat5e, Cat6?), but I've tested the speed using LanBench and got speeds in the order of 600-700 Mbps, which is enough, especially since the CF package I'm looking at is 150 Mbps.

The relevant part of the ground floor layout is:
Reception (front) - partition wall - Lounge (rear)

All I need is a wired connection from CF to the partition wall on the lounge side.

My question is: can I get them to lay the internal fibre patch across the reception and through the partition wall, and to put the ONT in the lounge?
It would require drilling a hole in the partition wall. If that's too much to ask them, I'm happy to drill it myself in preparation for the engineer's visit. Do you know how thick their internal fibre patch cable is, including the plugs?

Thanks. The reception room is not really used and the cable would be behind the wardrobes, so I'm not worried about that risk personally.

If the installer chooses not to do it, I can always buy a fibre cable and do it myself, which I'd prefer to using an Ethernet cable, as the latter would require a bigger hole in the wall and an RJ45 coupler.
