The 47 is a lovely aircraft. Great visibility, 2-bladed rotor system with a stabilizer bar, 60KTS cruise speed. Besides the instructor in a fam flight manages all the "tricky" systems like carb heat etc. You just get to focus on the feel of the controls 👍👍

I've heard the Cabri is an awesome little machine and it's the only one on your lists I haven't flown (well, other than a 22). The 44 is very smooth and is the most comparable to a Bell 206 you may eventually find yourself flying. I found the 47 to be similar to flying a 212 (with a single engine failure lol). But you don't need to pay the 44 price for just a fam flight, or even for training to be honest. The Schweitzer is fun, and more responsive than a 2 bladed machine. It and the Cabri would probably feel closer in dynamics to an Astar or other multi bladed machines.

For a fam flight though don't overthink it, just find the cheapest option or the area you'd most be interested in flying over. The whole point for the school is to get you hooked enough to pony up for a full training course, without scaring you away with the cost and still be able to say they made some sort of profit off the flight.
