Are LAN sockets still up-to-date? WLAN/wireless is the future!

For aesthetic reasons, I am still pondering whether I really want to hang the access point on the ceiling. I would prefer to have it somewhat more concealed, but I don't know how much less range / transmission speed I would have to expect then. Does anyone have experience with the Unifi Flex HD or Unifi In-Wall? Can you achieve similar values as with ceiling mounting? These two could possibly be placed more inconspicuously in the house.

Addendum: Could one not mount 1-2 Unifi In-Wall devices per floor instead of a conventional network outlet? The In-Wall would then replace the network socket, as it provides 4 additional LAN ports. This way, I save the network socket and the access point is somewhat less conspicuous. To compensate for the possibly worse range, one might have to install an additional access point compared to ceiling mounting.

What do you think?

So I installed the Ubiquiti In-Wall just below the ceiling in every hallway of the townhouse, and it fits absolutely perfectly. The range is absolutely great and everywhere totally sufficient.

We had the network sockets installed by the general contractor, because you can easily screw the In-Wall onto the frames. Just crimp the network plug on and it was good.

I also find them much nicer on the wall, since there are already lamps, outlets for the controlled residential ventilation, and smoke detectors hanging from the ceiling.

So you have one Access Point (In-Wall) per floor?

Edit:
In your picture, it looks like the Access Point only has 2 Ethernet ports. Is that then the In-Wall AC?

Exactly.

The quantity depends on the layout, but also on the installation height and your requirements.

At Goalkeeper, the parts hang just below the ceiling. If you want to use the LAN ports, then the parts have to be installed closer to floor level. However, then the Wi-Fi competes again with furniture and other things. So from my point of view, not so easy to compare.
