Looking for a more narrative-focused system than D&D 5e – any recommendations?

Hello!

I've been thinking about migrating my campaign to a different system. Right now, we play D&D 5e.

Our game is heavily focused on storytelling and roleplay, with very little emphasis on mechanics. We rarely roll dice, and most of the fun comes from the narrative itself. I originally chose D&D 5e because I'm very comfortable running it, but lately I've started to feel that the system's level of complexity doesn't really add much to the kind of game we play.

Another issue is that my players often want to do things that go beyond what their character sheets explicitly allow. For example, one hero might want to permanently cripple an enemy, while a slime-like character wants to stretch their limbs to reach something far away. In many cases, the rules don't provide a satisfying way to handle these kinds of actions.

Do you have any recommendations for systems that might fit this style of play better? Alternatively, if you've dealt with a similar situation while running D&D 5e, how did you handle it?

Thanks!
