Can sustainable construction such as SIP or eco-cement be modified with exterior stone? I'm looking to build a sustainable home in the French countryside, but want it to resemble the other cottages. Since most of them are over 200 years old and built with stone, it would be perfect to blend in completely.

Consider casting stone/concrete/rebar walls in a horizontal dry sand bed and then tilting them up. Then build a more conventional insulated layer inside this stone/concrete shell.

Stone can br added to any wall construction as a veneer. The foundation steps down 1.5 inches on the outside in what's called a brick ledge. Leave an inch of air space and build the stone wall outside the inner wall using brick ties so the inner wall holds up the stone wall rather than the opposite. Sedimentary rock like slate and limestone are easier because they are flat and dimensional. Some limestone quarries use a shear to produce brick-width stone. You are pretty much limited to native stone because shipping gets prohibitive quickly. So find a local mason and ask if stone veneer is practicable.
google 'brick ledge detail' for examples.

Go deeper than 1.5 if your climate has humidity and rain. 6 inch is the norm here. Also the terminology now is "thin veneer" or "full veneer". Full veneer needing the brickledge where brick or stone 3.5 inches thick sit on the ledge. Thin veneer is applied like tile to the wall to simulate full veneer. I would avoid thin veneer.

Depends on the transition. Above grade, with flashing and weep holes, I've seen walls with zero step down. Below grade ...
As for width, 3.5 inches is too thin for anything but lick n stick or super dimensional/reworked natural stone. Without rewire and backfilled mortar, you'd want six inches even for limestone. (Hung 40 tons of limestone on a farmhouse in Texas.)
The gneiss common here in the northeast would take 12 inches, at which point you might as well be adding interior walls to a stone house. That's why OP needs a crash course in French geology.
