For bagging a summit with some VF, the Graustock by Engelberg comes to mind. But two expensive lifts to ride to get near it, with some extra hiking. Rather spectacular views of N side of Titlis, but I did not feel that I got a good ratio of interesting _climbing_ versus time + money of lift-riding and hiking.
If snow permits, a better summit with more interesting climbing along the way I felt was the Bergseeschijen on the SW side of the Salbit granite peaks. Mostly SE facing, so some hope of it not being covered with snow. Parking at Goscheneralp at the end of the asphalt road rising up west from near the N end of the Gotthard tunnel. I liked it enough so that I put detailed route descriptions on the main USA climbing website MountainProject.com (with USA difficulty ratings):

I reached the summit by climbing the East Arete up from the Bergseelucke pass, which I felt was fun on sound rock, I think likely within the PD range. Anyway the paint-marked normal route is just a few meters away, so I'll guess it's not that committing.
Along the way up to the Bergseelucke are three interesting VF sections ... two on the Krokodil towers and a new one on slabs below the Bergsee hut - (none of them in the 2005 English translation of the Iris Kurschner print guidebook (www.Rother.de).
The rock on Das Krokodil was fun + interesting. Since I was using a special Skylotec Skyrider VF kit, I felt comfortable working out all the moves "free" with hands + feet directly on the rock, clipping the cable only for Protection, not Aid. The new VF below the hut I could not climb all "free", but still lots of interesting moves to play with, enjoying the special security of the Skylotec Skyrider.
If you prefer it more in "story" form, this Trip Report also includes detailed info for some of the other lower-altitude VF around Engelberg + Kandersteg (as Jonathan Lagoe mentioned above).
