Since all our tunnels are pre-drilled for rivets (and the pattern is fairly close), I don't think anything larger than a #10 screw is useful.
The "balance" between stainless steel, plated steel and aluminum material for the riv-nuts is ease of installation. Aluminum is easiest, but is more likely to gall or cross-thread with stainless steel screws. I would go with plated steel inserts myself. That's what we use in several other places on the car. But we have a $1000 installation tool...
