Ferrite bead pi-filter vs feed through capacitors in supply decoupling
All filters are voltage-dividers, having a SERIES reactance followed by a SHUNT reactance. What are your needs for these two reactances? Define those needs first.

The preceding components, and the components that follow your filter, must be considered.

And WIRES are part of the SERIES reactances. At 1uH per meter, if not part of twisted-pair or coax or over ground/power plane or metal chassis.
