There are mains side switches for many receptacle types. I use them on all my Pi's since it is easy to control where the power point is and the Pis tend to lurk behind/under stuff. Has the advantage of completely removing power when I want to and not creating any voltage drop issues.I have an in-line switch for my RPi 4, but I'm not sure if it can "pass through" the higher current from the Official RPi 5 power supply.The way I prevented that with the Pi 4 was to use inline USB-C cable with a switch. With the switch toggled to off the Pi didn't have power so couldn't boot. The same switch could be used with my Pi 5 if I wanted.
I have some inline switches that work fine, other than not ended up in optimal places, and have some that cause issues with Pi 3B+ and 4B. I have not seen any that work with a Pi 5 USB PD connection since they would have to pass through the full connector set. I suspect some exist, but could see weird behaviour if the inline switch only switches the power lines and not the control lines. If you don't pass through the control signals you will break the USB-PD negotiation and your Pi will treat the USB-PD supply as a dumb 5V supply, and throttle the USB port power, if you don't override it. That is the other advantage of the mains side switch, since it does not mess with the downstream USB-PD stuff.
