The quality and difficulty of hikes in the places you have named vary tremendously.
One way to get some ideas is to study the options in -
Another is to look at topo maps. Can you read them?
If so, we can link you to maps that clearly show the difficult terrain.
For one example of why that may be useful-
There are no easy hikes on Pilatus. There are short walks around the top.
There are lots of hikes on the Rigi, most fairly easy on good quality trails, but many have large altitude changes. So, your comments in #3 are puzzling to me. See Pilatus images attached.
So, when you say " We do not climb mountains" I have to ask, do you mean that you do not do technical climbing, or, that you don't go up easy paths that have a substantial altitude change?
This website may help you understand the trail marking system:
If you work this map (below) , and turn on "Hiking Trails" in the menu, and look around variuos areas, you will see a few trails that are blue. They require technical climbing...ropes, crampons, pitons, etc. The red ones only ask for boots and hiking staffs, but can have huge altitude changes:
I have set this map with "hiking trails" turned on in the menu, and focused it on Schynige Platte:

My experience says that there a some short, fairly easy trails up there, but all are rugged ..not simple and smooth.
I do not know what you mean by "what kind of platform."
The hikes you have mentioned are mostly are above the tree line. The Rigi is an exception, but Rigi Kulm is above the tree line.
To understand hiking, it is extremely important to know when you are going.
Trail availability and difficulty vary a lot during the fall months; altitude is critical. There can be snow at high altitudes while everything is easy at lower altitudes... There was snow at Männlichen a few days ago.
Could you please give us bit more idea of when you are going to various regions?
