Upgrading DSL to Fibre - what will i get?

[turgid]

I've had 75Mbs/25 DSL for a long time at 500 Baht a month and am now thinking about upgrading to 599 1Gbs/500 Fibre BYOD  (i provide the routers and network).  I dont know how fibre works with regards to home networking so be gentle.  

The Fibre  installation fee is 4800 Baht but they absorb it if you contract for at least 12 Months. However  the sales folk are very vague about what installation includes.

 

I live in a two bed apartment. At the moment i have a wired TV, NAS, Desktop PC.   Scanner Printer, various phones, appliances  and main bedroom TV on WiFi.  There is a wired backhaul from the under the TV DSL  ASUS  WiFi 6 router to  an  Archer BE800 WiFi 7 router in the spare bedroom / office.

 

I  have the  WiFi 7  router which i use to stream my Desktop PC to a VR headset but  WiFi 7  speed drop off is brutal at about 5 Metres so I need to ideally  have the WiFi 7 router wired in the centre of the apartment.  I've tried mesh networking but I have an agricultural noisy  NAS banished to the  office room and the only way I could get stutter free performance was with a wired backhaul.

 

I understand from the internet that  the incoming fibre usually terminates to something called an ONT or optical network terminal fibre to ethernet adapter  which ideally I want to be in the middle of the apartment but i suspect will be drilled through the utility riser in the corner of the hallway.

 

Anyone have practical experience of AIS Fibre, what the installation provides and what the actual Fibre to Ethernet termination is ?

I'm guessing i will have to run 40 metres of Cat 7 cable around the apartment from the hall to under the TV  but i'd really rather not.
