Multiple smaller capacitors on power rail for NeoPixel / WS2812B strip
I read in the AdaFruit guide that a 500-1000uF capacitor is recommended on the power rail.
However, electrolytic capacitors in this capacitance are quite large. Depending on the length of the strip, ...

Is there a shielding difference from switching terminals of an MLCC capacitor?
For electrolytic capacitors, the capacitor has only one working polarity (or it
usually will get damaged if reversed).
For film capacitors, the outermost metal layers ("left" and "right&...
