I’m with you, I’m not sure the volume or cost would be less once you factor in capacitors that are high enough quality for the application.

The datasheet mentions low profile a lot. That does make sense as one can make a flat, high quality, capacitor. Making a flat high quality inductor is harder and probably more expensive and likely consumes more volume overall. I can imagine some applications where being flat is important, like the back of a panel.
