There's really no way for someone sitting here to answer that question. Put the settings to whatever you need to get the shutter speed and DoF you want. If the light is low, bump up the ISO; if the light is good, don't. There are no magical wedding settings. As you know, your cameras are pretty darned good at high ISOs, so just do whatever works.
