Network switch

I'm considering buying a network switch, and keeping an eye on PB Tech's Cyber Monday sale later today to see if this may offer a good deal.

In our first lounge I'm currently using a Fritzbox 7390 which has four LAN ports, but one of these is occupied by the fibre internet connection, and a second is wired to a TP-Link router in the second lounge, acting as a wireless AP to boost the reach of the wifi in our house, and also offers wired connections to the PC, NAS, and Raspberry Pi in that room. The other two ports on the Fritzbox are occupied by another PC and another Raspberry Pi, but I also have an Xbox 360, a Bluray player, an AV receiver (with Airplay for music), and a TV which could all benefit from a wired connection. Clearly, I have too few LAN ports for my needs.

So I'm looking at getting a switch to ensure that all my devices can connect via a wired connection. We are also looking at turning our second lounge into a bedroom in the near future, which means that the tech in that room will largely be mothballed or relocated to the first lounge (though I'd like to keep a wireless AP in that room to improve signal reception in the house). By my calculations, I'll have need of about 8-10 ports in the first lounge.

From my research so far, I figure I don't need a managed switch, but I think it would be good future proofing to get a gigabit switch. Any recommendations? Going back to PB Tech (in the hope that the Cyber Monday sale offers a good deal in this area), and on the basis that I've had good experiences with TP-Link, how does this switch look?

16-ports is a lot more than I need right now, but I figured it gives room for expansion down the track.

As to how it's used, would I need to keep the Fritzbox connected to the ONT (and connect the Fritzbox to the switch) or could I just connect the switch direct to the ONT? If I can connect the switch directly to the ONT it would remove some of the clutter and I figure it would give me a reason to get a better wireless AP in its place...
