Yet such information is incredibly lacking and hard to find. You would think the Vatican and similar would have all this information ready to be digested by people interested in learning, yet it's incredibly hard to find if it's available.

Unfortunately we Catholics often try to 'dumb' down our theology and liturgical training to make us seem more approachable like protestant churches. This acheives the opposite of the desired effect: the 'motions" begin to feel pointless. Ritual is important in human life, and symbols are important. But without good education, the symbols and rites are empty. Which it seems like what previous commenter was experiencing at Easter Mass. Granted, it's entirely possible even after learning the meanings that they would all still seem unattractive to commenter. But at least he wouldn't be missing a key element.
