Caves of Qud does not enforce permanent death. Neither does Dungeon of Dredmor. The runs are also very long, as in usual RPGs. So you definitely CAN enjoy these games if you do not like permanent death. The good way to think about roguelike in traditional sense is not "if you do not enjoy permadeath, you won't enjoy it" but "you might enjoy it so much that you will want to play it permadeath".

(In Cogmind it is also optional although there are some caveats, Jupiter Hell is a short game so you won't lose much if you die. I do not know about Dungeons of Endless.)

The fun thing (and essentially the original definition of roguelike) that you control the flow of time. Technically it is turn-based but so different from other turn-based games that the genre got a special name "roguelike" and not dungeon-something. (And Caves of Qud is not really a dungeon crawler anymore than Minecraft or Terraria are, which are structurally a bit similar.)
