Ok, so ds.rolling.mean allows for min_periods while ds.rolling.construct.mean allows for fill_value?

Yes. Originally, construct method is designed for more advanced use cases, such as strided moving average, weighted mean, short time FFT, etc.

On the other hand, using skipna=False resores the default behaviour or ds.rolling

It is not strictly true. min_periods also considers nan values that already exist in the original array. This behavior is the same with pandas rolling.
