Thanks for the dates. A lot of the Alpine cableways are shut down then for between season maintenance so you won't have to worry about riding one of them. ;-)
<<"To get the experience of the Alps, in a save non height way">>
Not sure I understand that fully.
However, one option is to go by train to the Jungfrau region, which you enter from Interlaken Ost ,the gateway town, then take the train into the valley to Grindelwald or to Lauterbrunnen, which are both valley towns. Then ride the cograilway which runs every day of the year from either of those towns up to Kleine Scheidegg and then down to the other, and , eventually back out to Interlaken and the mainline Swiss rail system. Change trains at Kleine Scheidegg. Great views of the Alps, rarely any sensation of being suspended i the air because you are in a small train.
This map shows most of that journey from Interlaken:
Note the "32" at the end of that URL. That is the zoom level at which the train lines pop up clearly. Lauterbrunnen and Kleine Scheidegg are just off the bottom of the map as shown Scroll, like so:
....if you zoom out, the rail lines disappear.
You can look up the train schedules...frequent service... between those locations and also to.from Zürich in the SBB timetable. We strongly recommend that you check this web site first...useful tips and tricks:
The actual SBB website is full of good information in addition to the schedules, and you'll want to access it often:
The restaurant at Kleine Scheidegg is well know for its very good Rösti ( hash brown potatoes, particularly well done throughout the German-speaking part of Switzerland). In the French-speaking region you get fries - les frites. ;-).
and also for the Apfelküchen with whipped cream.
At Kleine Scheidegg there is a branch line that makes the very expensive trip up to the Jungfraujoch...which may not be consistent with your acrophobia.
That page has descriptions of the various towns near the Jungfrau.
I don't think the lake boats are running at that time of year on the two large lakes of the Bernese Oberland _ Lake Thun and Lake Brienz.. In German, der Thunersee und der Brienzersee.
They are a nice way to look up at the Alps. However, the namesake towns are worth a walk around, and the castle at Thun is a very interesting building to explore.
