How do smaller capacitors filter out higher frequencies than larger ...

If the capacitors were ideal, there would be no way that smaller value capacitors could filter better at higher frequencies. But every ceramic cap maintains a capacitor-like behavior up to some frequency. Then the parasitic inductance starts to assert itself and ultimately, at high frequencies, dominate the impedance characteristic.
