Hi, I was asking those small capacitance denoting what properties

Input capacitance. Think of it like Miller capacitance in a tube. That capacitance has to be driven. If the drive impedance is too high then the high frequencies will be lost.
The lower the capacitance is the better the part is for making a CCS.
In cascode the capacitance goes way down. That is why cascode is better than single.
