I believe in really good onboarding material. i came in with the 1983 Basic set, which has still never been equaled for getting 10 year olds capable of playing and GMing in short order. 2014 5E has some good starter stuff, and one assumes that will continue in 2024 5E.
But the actual game should be written for general users, neither beginners nor masters. Filling rule books and adventures with handholding content makes those books less useful even after a very short period of time. Trust people to be able to figure it out. they will.
