I'd say learning an instrument is definitely one of those things that don't necessary have a direct impact, but can be a blessing as an adult. Basically, it avoids a common regret (I never learned an instrument, but I don't care enough to spend the time to learn it now that I'm hitting 30) and provides a way to get into music (instruments or not) with less investment. It opens possibilities for a number of hobbies. Sports are a great way to learn social skills. In order to participate in a team sport (consistently) you need to learn how to deal with people that aren't as pre-selected to your taste as the friends you make in school. You also learn something other people may be worse at than you, which can help with confidence. Especially if the more experienced players are encouraged to train beginners. Most other things are just examples of these or should already be (partially) covered in school, depending on your school system. Many of these should be recreational for the kid. For example, if they hate instrument practice but can read music and understand the basics, I don't see any harm in replacing it with something else at some point. In the end, you just have to be good enough. My childhood left me with a few issues, but most of them sorted themselves out in early adulthood. Just keep this in mind: the reason there are so many opinions on what is the "right way" to raise a child, is that every parent is afraid of doing it wrong. Most advice is anecdotal and the reason people feel strongly about it is that they don't want to have been wrong, not that "it just works". Disclaimer: am not a parent.
