Switch with separate installation for SFP / SFP+

Do everything centrally and distribute from there. Everything else makes no sense for a single-family house. Buy yourself a larger switch with enough ports.

Wifi with more than 1gbit????
But not full duplex and therefore significantly slower even with only one client.
We are not talking about lab stuff or what is not yet available on the market.
I am not aware of any wifi that is supposed to be faster than a 1gbit LAN connection.

I said theoretically — more to illustrate that 10GBit is no longer rocket science nowadays. The Flex HD is specified at 1733MBits.

Most devices on the switches will never be able to fully utilize the 1GBit, that's clear.

That's why investing in it now is a waste of money.

But even in the home user sector, there are many use cases where 1GBit is annoyingly slow. Whether it's simple file transfers, backups, or working with larger amounts of data over the network. At 100MB/s that's often not very practical, at 500-600MB/s it looks quite different.

Why is that not practical? Even the file servers of our customers are only connected with 2x10Gbit, and there are several thousand users working on them simultaneously.

Why should I buy hardware (servers + hard drives) that can handle 500-600MB/s throughput when my end devices are connected with 100Mbit (Wi-Fi) or 1Gbit (cable)???

Yes, that will come eventually, but I stick to my point: The switches will then be hopelessly outdated. So just lay CAT-7 cables and that's it. You can always connect later via 10Gbit. Anyone who doesn't know which SFP modules or fiber optic cables they need will face major problems in case of defects. Why does it have to be so complicated when it can also be simple?

Wifi 6 (AX) will deliver well over 1 Gbit/s. This will also require connecting the access points via multigigabit switches.

Of course, one could say that such bandwidth is not necessary in home environments. However, I know at least a handful of people for whom the connection between floors with 1 Gbit/s was not sufficient. Often the NAS (with 2 x 1 Gbit/s) was connected in the basement. All devices push their backups there, the TV streams from there, etc.

And yes, you can also do 40Gbe over copper on the short distance... but it is simply more expensive than 2 MM SFP+ and a bit of fiber optic cable.

That's why investing in it now is a waste of money.

I said "most". If you connect the critical path, where you would like more than 100MB/s, with 10GBit, that's not a waste of money. (And in my opinion even quite affordable if you get a small 10GBit switch for the important devices)

Why should I buy hardware (server + hard drives) that can achieve 500-600MB/s throughput when my end devices are connected with 100Mbit (WiFi) or 1Gbit (cable)???

Of course I connect all end devices with 10GBit! Nowadays, that's not a significant investment at all for NAS, desktop PC, and laptops.
