Regarding Insulated Concrete Forms for a finished basement, what is the preferred type of wiring if the insulation is 2-1/4" thick w/ furring strips and drywall? What is the most cost effective? My gut tells me steel boxes w/ EMT set in the forms at they are being built and add an extension ring to each box, ending with a plaster ring. Thoughts??

Run like hell in the other direction no just kidding cant help ya there, but htought i'd let you know someone has read your post lol

Foam is on the outside of the concrete? If so use a hot knife and romex after the concrete is poured. Throw in some PVC sleeves for any exterior penetrations and your all set until rough. Hot knife blade was a U shape and we put the foam back into place after we shaved it to fit the wire.
