Hello IzramD Sydney
Thanks for your kind words. We are happy to year that you will be visiting our country in June.
Before replying to your question, I want to clarify a misunderstanding. The SwissPass is a resident’s product, while the Swiss Travel Pass is what you are going to use. This is why you have seen the SwissPass for seniors.
No, the Swiss Travel Pass does not offer a senior discount. It exists in three versions:
You can find the options here:

Is the Swiss Travel Pass the best ticket? It depends. As you have noticed, the Swiss Half Fare Card plus point-to-point tickets or together with a Saver Day Pass could work as well. The great advantage of having the Swiss Travel Pass is that you will not have to lose a thought on the ticket purchase (except for mountain excursions).
I do have a little issue with your itinerary. Have you been to Switzerland before? You are planning 4 nights in Chur? Is there a reason for it? Are you planning to take the Glacier Express from there?
Honestly, I would not even spend a night in Chur. On the other hand, you are going to give one of the most beautiful cities in Switzerland a miss: Luzern.
Also, skip Saas Fee, not worth a visit. You should rather visit the Bernese Oberland, the area around Interlaken, or even Grindelwald / Wengen / Mürren. Also, a night or two in Zermatt would make your trip unforgettable.
I think it would make sense to have verified your itinerary in one of the Switzerland travel forums, where locals, as I am, can comment on your planning. One of the good travel forums is from TripAdvisor: https://www.tripadvisor.com/ShowForum-g188045-i336-Switzerland.html. I spontaneously thought of user Hambagahle, she is a prof what concerns travel in Switzerland for seniors.
Kind regards,
Roland
