Hi Swati-
What to see and where to go in a short trip to Switzerland is full of difficult decisions.
Certainly a train ride from Luzern to the chocolate factory at Broc, with some selection of the route, offers very scenic train rides
I have posted above in another post some images of the area near lake Lucene.
The remaining issue in my mind is whether Zermatt is the best high alpine area to chose. I recall that it is a favorite area for Annika, and I have not spent much time there, and not for many years. So, I do not have a good perspective on the area.
I have chosen to spend my high alpine time in the very large and accessible area near the Jungfrau. I like to walk in the area and absorb the views.

I have attached a few pictures of the area in this link:

Depending on where you might choose to stay in the Jungfrau area, train access to Broc and Zermatt is easier than from Luzern. Interlaken has excellent rail connections and is close to Bern, where you can catch the train to Paris.
See attached screen grab.
However, Interlaken is not the most scenic town, and the experience is much more alpine at towns further in the valley, such as Wengen, Grindelwald, etc. Those all add travel time if you want to travel away from the region.

The short walk from Männlichen to Kleine Scheidegg is one of the best in Switzerland for views of the amazing landscape. It is famous.

You might consider the area as an alternative to Zermatt.
