I know things like stereos need power for memory, or some coffee
makers with timers need power for internal clocks, but do appliances
like kettles & toasters still use electricity if they are off?

Not unless they have a clock or timer or some electronic control. If
they have a standard rocker or toggle switch then turning the switch off
turns it completely off.
