Language is optimized for speech not writing. So it’s not exactly what you’re looking for, but very similar. “Human speech may have a universal transmission rate: 39 bits per second No matter how quickly you speak, you still share the same amount of information” (https://www.science.org/content/article/human-speech-may-have-universal-transmission-rate-39-bits-second https://www.science.org/content/article/human-speech-may-hav...) As for writing efficiency I would say Korean Hangul is the best writing system in the world. It combines the best attributes of alphabets and syllabaries. Also western writing systems aren’t as simple as they seem. Every letter has multiple forms upper/lower and print/cursive making at least 4x (cursive forms often vary depending of location within a word) as many forms as you expect.
