Is it ok to say for all domains greater than 10km, we should use culumus options, and for domains less than 10km we can use microphysics options?

In the youtube video (, it is mentioned that there are specific options in cumulus scheme which are appropriate for 3km to 10 km. Could you please mention a couple of popular options to use in this case?

Thanks in advance,
microphysics should always be turned on no matter what resolution you are running.
for grid intervals larger than 10km, cumulus scheme should always be turned on.
for grid intervals smaller than 3-4km, cumulus scheme should be turned off.
3-10km resolution is the typical grey zone, and there is no consensus whether we should run with or without cumulus scheme. In this case, a scale-aware cumulus scheme could be a better option.
