Is there a philosophical worldview which is similar to absurdism in that it denies the value of meaning in the world, and thinks it is ultimately better to live a life without the concept of meaning, but still fully accepts rationalism?

So, after reading the Myth of Sisyphus I felt as though whilst I found myself agreeing with some points of Camus, I felt his overall conclusions in relation to reason and "the absurd" I didn't, and I was wondering if theres a worldview that matches my requirements stated in the title? I've heard of "optimistic nihilism", that being the concept of a "meaningless world", but we should just accept this concept and live our lives as normal, but I find that still in some sense holds value to the concept of meaning, in a way which I am not interested in.
