Full Fibre Installation - Wiring before install

[shopper150]

I'm currently carrying out a refurb at a property where I intend to have Full Fibre installed.
Is there anything I can do in now in advance of installation to make the wiring neat and match the rest of the decor?

I've had the telephone sockets and main junction box redone, that was easy as I'm familiar with the traditional telephone wiring. Am I correct in assuming Full Fibre will not use that BT line coming into the house?

Can I do my own 'first fix', (of half fix) now? And they then join it and run it to the main box in the street? What cable to I need?

I assume the cable coming to the property from the telegraph pole will also become redundant?
