On my amd64 machine (with Ryzen 1800X CPU) 'schedutil' is enabled and set as 
default, so the above statement is a bit too simplistic.

What is relevant in this context is that CONFIG_CPU_FREQ_GOV_SCHEDUTIL depends 
on CONFIG_SMP, which is not set on config-5.10.0-8-rpi and it's probably not a 
good idea to change that as the RPi 0, 0w and 1 are all single core.
So 'ondemand' seems to be the proper choice, just for different reasons.
