The latency and signal attenuation from an extra 7 meters of cable would cripple even the most latency insensitive tasks.

You’d never know the difference, there are other slow downs that cause real latency issues.

Given OP’s post history, this was AI generated. Nobody writes like this.

As a mental exercise, the “optimal” solution is a Ubiquiti or similar mesh network.

Your question is too broad,.

If you have “delay start” functions on your washing machines (dish & clothes), you can either do dishes overnight or clothes overnight as close to 3-4am as possible (assuming you’re waking up around 6 or 7).

There is not a great way to “automate” the heating of water in a traditional water heater and it would be a safety hazard to do so.

The only other good option is an inline electric water heater, but the cost of that will outweigh anything else.

If you’re eager to spend money on this, I’d look into newer appliances that you can set to run at a certain time of day if there is absolutely no functionality available.
