A Swiss Pass would definitely be the most convenient option, as you don't need to buy tickets for many of the trips, not even for the Rigi trip as that's included for free. Whether a Swiss Half Fare Card is cheaper requires some calculations as explained here. In any case, be sure to look into the pass discounts (click the Discounts tab on the pass pages I referred to).
Please note that there is no 1st class Swiss Half Fare Card. A Swiss Half Fare Card is not purchased for a specific class of service. The discounted tickets you buy with it can be 2nd class or 1st class. You would need 3 Swiss Half Fare Cards. The child (if under 16) travels along for free with the Swiss Family Card, regardless of which pass you choose for the adults. There is no 1-day Swiss Pass, but there is a 1-day travelpass for Swiss Half Fare Card holders (see here). Your plans do not look like you would need one of those.
Hopefully this helps to make a choice. Have a great time in Switzerland!
