Hi, 

With Sky Fibre, you'll be using BT Openreach's Fibre 'VDSL' standards (Not Virgin's DOCSIS) so any router/modem you select will require compatibility with this system.

I haven't been a customer of Sky's for some time, so I'm not sure if they still have restrictions on modem/routers you can use on their network (they only allowed their own branded ones when I used them) so you'll need to also confirm this with their tech support team (although they struggled identifying the difference between ADSL and Fibre, which was a big red flag for competence on their part, so be warned). 

If everything above checks out, then you'll need to have an idea of what your home's layout is, a decent idea of distances between the far corners and the main phoneline plug to get a gauge on whether you really need a mesh or not, as sometimes it's overkill, others a requirement. 

If you aren't needing a mesh system, the VR2800 (https://www.tp-link.com/uk/home-networking/dsl-modem-router/archer-vr2800/) might be sufficient, although with personal experience, they may not last the 3 year warranty due to the 5Ghz chip failing. 

The above works well with the AC1300 powerline adaptors I had in my network including the Wifi model (https://www.tp-link.com/uk/home-networking/powerline/tl-wpa8630p-kit/) as an extender. 

If you are looking at mesh, and specifically TP-Link, then I'd advise getting one with a dedicated backhaul channel, like the M9 (https://www.tp-link.com/uk/home-networking/deco/deco-m9-plus/) as this will be more likely to handle the throughput of the number of devices you have (although I do have an M5 3-pack and they seem OK with a similar number of devices as yours, I'm just not sure how well they'll cope if there are a lot more high-bandwidth devices than I have already (3 laptops, 2 servers, 2 tablets, 2 smart TVs, several phones).

As always, make sure you Google reviews of any products as there can be details of any 'gotchas' or potential common faults which you may, or may not, be affected by.
