If you are going all the way to Jungfraujoch, I would strongly advise against stopping anywhere 'in between' as it will be a tiring day. Health wise you should be aware of the high altitude of the Jungfrau area , as you will start and end the day at (for Switzerland) a very low altitude.
If you want a break from riding on the train all day, you should pause for 1 hour at the intermediate places on the Jungfrau area railways (eg Wengen)
