ᐅ Is network planning for a new semi-detached house useful or possibly overkill?

Hello everyone,
here is the starting situation:
A semi-detached house with 3 floors (ground floor/first floor/attic). There are a total of 12 network ports ending in the utility room. The Magenta 250 plan will be ordered. The 12 cables equipped with keystone modules run into a patch panel and from there into a Netgear GS116PP PoE switch. From there they go to a FritzBox 7590AX (modem + router).
In the living room wall on the ground floor (inWall HD, I reacted too late here, so no preparations were made in the concrete ceiling for the ceiling construction) and in the hallway ceiling on the first floor (Nano HD, as the drywall ceiling is still to be done), 2 Ubiquiti Wi-Fi access points will be installed to provide wireless coverage for the house and garden.
One TV, two PCs and one console are initially connected via LAN, the rest via Wi-Fi. Otherwise there are smaller smart home devices like Shelly actuators for the shutters and typical Hue/Alexa stuff. We will not use fixed-line telephony.
Yesterday I had a thought in bed: is the FritzBox I bought enthusiastically overkill because I hardly use it? I will presumably disable its Wi-Fi function, so I won’t benefit from Wi-Fi 6 since the two Ubiquitis will take over that task.
Should I rather go for the Wi-Fi 6 versions of the two Ubiquitis?
The router has 16x PoE+, but it is unmanaged, which apparently can cause problems with MagentaTV because it uses multicast. So far, we do not use MagentaTV but other providers who apparently stream via unicast, so there are no issues. As a typical user, are there other disadvantages to using an unmanaged switch? I do not use VLANs, etc.
The NanoHD in the hallway ceiling on the first floor probably won’t provide coverage “upwards” into the finished attic, right? There are two duplex ports in the attic where our desks are planned, so I could still install an access point there if needed.
AVM does not make access points for ceiling or wall mounting, correct? I’m worried that even the Ubiquitis might be overkill for my situation and that integrating AVM access points would be much simpler and more practical. But now that the preparations for wall/ceiling installation are already done 🙂

I would appreciate your comments and advice.
Best regards

The switch must support IGMPv3. If it doesn’t, there can (and most likely will) be issues when used with Magenta.
Otherwise, this approach is fine. The Unifi APs are not overkill either.
Whether you will get reception in the garden from inside the house is another matter.

A 7520 or 7530 model would probably suffice. Since there's only one LAN cable connected through the switch anyway, the smaller Fritzboxes also support DECT. If it doesn’t cover the whole house, you could use a VOIP DECT base station like the Gigaset GoBox, which you can connect somewhere to the LAN and place conveniently within the house. Is there anything specific the FritzBox needs to be able to do?

Very good point. We chose the 7530 AX. Not because of WiFi 6, but because it’s fairly new and will receive updates for quite a while. WiFi and DECT are disabled; the box is only used for DHCP, routing, and partly DNS. The Gigaset GoBox is placed hidden in a cabinet in the living room, serving the ground floor, and upstairs there is a Gigaset DECT repeater covering the first and second floors.

That would also be my argument for choosing a newer version of the Fritzbox. It’s better to buy a more recent model and get 2-3 years longer support with updates.

Since the transmission power is limited in Germany, the Unifis have a similar performance level as other decent products. There’s nothing overkill about them. In terms of price, they are comparable to other manufacturers.

We don’t use landline phones.
The long update support was the deciding factor for the FritzBox (FB) – I don’t really see much additional benefit right now. It’s a shame; I was hoping you could convince me not to send this great device back 🙂
So I’ll stick with the 2–3 Ubiquiti access points and not switch to AVM. Then I’ll disable the FritzBox Wi-Fi.
Do you think it makes sense to replace the switch with a managed switch? We don’t use MagentaTV so far.

Since I have a 16-port switch (I specifically chose one with all ports aligned side by side so I can wire symmetrically from top to bottom to the patch panel), I’m currently looking for a 16-port keystone patch panel.
For a 16-port, I only seem to find the "blank panel" without any structure behind it:

I would prefer something like this:

, where I can also secure the patch cables behind it. What do you think?
