MC carts are affected by capacitance. Its just that the values are generally much greater than those that affect MI or MM carts, due to their much lower source impedances. It will affect HO MC more than LO MC.
On the vinyl engine site there is a calculator that can compute the impact of cable/preamp input capacitance on any cart, including MC, if you know the source resistance and inductance of the cartridge. Look under "database tools":

Then down to "Cartridge/Amp Loading/Resonance"
Input the resistance and inductance for your cart, and input capacitance values to see what the resonant frequency is. I think anything above 20 KHz is fine, so capacitance values up to that resonant frequency should be OK.
