Need help with my itenary

Hi,
We are planning to visit Swiss as a group of 3 family with kids (around 6 all above 12 except) for 4 nights. After I read so many information in the internet and this forums, I have come to conclusion that I need to pick one moutain(mt pilatus or mt titlis or mt jungfrau or matterhorn), one lake view and cities tour like zurich/geneva/interlaken so that I get a glimpse of Swiss. I understand berner oberland area is one of the place not to miss. Here I need suggestions to pick one mountain and lake.

1. Zurich, Lucern city,mt titlis , interlaken , geneva, lake geneva/lake lucerne/lake zurich(either one of the lake)
2. Zurich, Lucern city,mt titlis , interlaken , mt jungfrau, geneva,lake geneva/lake lucerne/lake zurich(either one of the lake)
3. Geneva, lake geneva,interlaken, zermatt matterhorn

There could be number of options. I would need experienced or most visited people advice to choose the best itenary.

Thanks in advance for your help!!

Thanks
