I'm not sure what problems you're running into with decoupling capacitors. I find this to be the easiest part of my designs. If the datasheet has specific requirements, do that. Otherwise, 100n capacitors on each power pin. 50V 100n capacitors can be found all the way down 0402s, and there's no sense in using anything else. Dielectric doesn't matter much for decoupling. Increased cost due to an additional BOM item is way higher than the fraction of a cent of a cheaper capacitor.
