Hi loksat and welcome to MySwissAlps!
To know for sure the best rail pass for you you need to do the math on our web page: How to choose the best rail pass. There is an Excel sheet there to help you with the calculations. You will need to plan out all or at least most your trips by bus/train/gondola/boat around Switzerland.
You will want to compare the Eurail Select Pass (8 or 10 days) to the Swiss Travel Pass (either 8 or 15 days). Both pages have links on where the pass is valid (use the PDF maps) to compare.
As you are in Switzerland, traveling around for 14 days, you may want to get the Swiss Travel Pass instead; as the coverage in Switzerland is better, especially for city transit (which the Eurail doesn't cover).
If you want the 25% Jungfraujoch discount you will need to use the Eurail Pass (or Swiss Travel Pass) that day to get the discount). In either case you should travel to Jungfraujoch on a day that is covered (partially) by either pass. Again the discount is a bit better with the Swiss Travel Pass and it is an expensive trip even with discounts!
