I never suggested WIMA FKP2s, did I . FKP1s. I liked your post. It takes a MINIMUM of 3 bypass caps, and up to 7 or 8 , in any one location, to get it right !! SO, its not just cap types, but cap VALUES also, each play a different part of the spectrum.
The smaller uF values need to be explored, assuming one has a well implemented wide-band system to reliably make such determinations.

Thats easy, no ONE capacitor does the entire audio spectrum in a LINEAR and optimum way.
The Cs in my DIY A7-800 crossover use about 4 caps in each and every "C" position . My tube amps, with an all-film-cap supply, may use 3 to 8 bypasses at each " C " location.
Its determined by ear, listening to music, if your system is well implemented, great amps, wiring, etc..
