but seriously I would love to spend time in the mountains
Look out for Göschenen, Andermatt, Zermatt, St. Moritz, Davos, a region called "Oberwallis" and the Jungfraujoch if you want to spend time with mountains. This train line could be interesting[^]. You travel 7.5 hours through the mountains of switzerland, from Graubünden to Wallis.
Using the Glacier would bring you to some of the nicest places of switzeland and the Glacier is also one of the world's most famous train lines. See details here[^].
You can see famous things in all of the previous mentioned places, specially the lake lucerne is very well known.
The only thing I'd add is watch the laws: the Swiss are generally very law abiding, and they seem to hate motor vehicles with a passion. You must for example turn off your engine if the car is stationary - large fines are levied if you don't. Alcohol limits are pretty low, so the best advice is "don't at all, even the next day" - you can be punished for being a passenger in a car being driven by someone who is over the limit!

But it is a beautiful country, with friendly people and well worth a visit.

Switzerland doesn't like US$. They use Swiss Francs but will accept the euro. Changing US$ to Swiss Francs should be ok but changing US$ to the Euro would mean the banks change it first to the Swiss Franc and then to the Euro, involving two commissions and two poor exchange rates. (This was my experience at a bank in a village.)
Eurail Pass doesn't work on private rail lines. Have Swiss Francs or Euros as they won't take US Dollars on the train or a credit card. Being stuck on a train between Interlocken and Grundelwald with only US dollars and credit card and a Eurail Pass wasn't fun! The ticket-taker talked to his supervisor on his cell phone and we were finally able to give him US dollars. Otherwise we would have been offloaded at the intermediate station, I suppose.
Lost a backpack due to carelessness with 4 US passports and $4,000 in cash. Went back within 30 minutes to the station and was told no backpack was found. Same answer the next day too. Reported it to the local police the next day and he said it was impossible for the backpack not to be found, got on his motorcycle and rode off to Lautenbrennen, and retrieved the backpack for us, with passports and all the money intact!
As to friendly Swiss folks, forget it, they don't smile at all. Polite, yes; friendly, no!
Don't go up Jungfraujoch on the private rail line. Unless you want an Indian experience! The restaurant on top was named "Bollywood", played Hindi film music and half the visitors spoke Tamil or Hindi.
That was my experience as well. I dated a German-speaking lass and I went to visit her and her family in Zurich. I was not invited to stay with them so I put up for the week at a well-run small hotel. The owners were a tad too formal and polite. Her parents looked on me as a sort of social misfit which is fair comment as I had long hair, rode a BMW bike and it was the decade of the Baader/Meinhof gang after all. During the day, lass and me would ride off somewhere and drink excellent beer. The mountains in the south were spectacular. Yeah, a very pretty country for sure and from where I sat, it had one major fault, they don't play rugby. I never saw her again after that brief visit but she was a fine lass. If they'd have played rugby I might have married her.
