Radiator leak?...
I'm having a hard time picturing how a radiator leak could have water (coolant) in the cabin. In fact I'm having a hard time picturing how any coolant leak could have water in the cabin, other than perhaps a heater core leak.

If the car sat out last night did it rain? Was it a dewy night? Any chance a nearby sprinkler sprayed the car? Any chance you left a water bottle in the car and its rolled around under the seat and developed a leak?

Oh, before I forget, regardless I think you need to check the water drains both at the front of the car and on either side of the top under the clamshell.

If those are dry show no signs having any water collected in them then you have to look at the water getting in another way.

If you are sure it didn't rain on the car last night, and there was no heavy dew, IOWs, absent any outside water source then the water has to be coming from somewhere in the car. Coolant is a possibility, but as I touched upon above you should be able to distinguish water from coolant.

If you are sure the water is plain water, at least not coolant, then that leaves the possibility water has leaked in through a leak in the top, around a window, some place, and over times seeps out and collects at the lowest point in the cabin. You need to feel around and see if you can find any damp place that might point you to this reservoir of water.

Coolant is a possibility, but as I touched upon above while I can't see how it could get in the cabin you should be able to distinguish water from coolant.

You need to feel around and see if you can find any damp place that might point you to this reservoir of water.

This I think has to be a slim possibility. But like the water drains/basins you need to be sure.

Antoher source of water, and this is I think a more likely explanation, is the A/C evaporator water tray/drain is plugged this collects water (condensation from the evaporator) and it will pour out over the top and run into the cabin.

LIke the body water drains/basins you need to check this is not happening but I can't tell you how to do this, as I've never had to do this.
