They appear like really awful inductors, which means they still exhibit a usefully low impedance well beyond their SRF. (Notice how SRF curves almost always appear on log-X plots.)
It's more instructive to think about the capacitors' physical construction than it is to run them through SPICE and call it a day. An MLCC is just that -- a multilayered construction in which numerous smaller capacitors, each with a somewhat-higher individual SRF, are effectively paralleled. A SPICE model that looks like a capacitor in series with an inductor and a resistor isn't entirely adequate to capture all of the subtleties.
