NCO in the Army is a vastly different situation than a commissioned officer in any branch, and each workplace is going to differ in terms of idiotic bosses, harsh environment, intellectualism, and tolerance for innovation and invididuality. The rest of your items (chain-of-command, blind following of orders) are going to be present in some form everywhere in life, and you're welcome to push back on those if you're careful about how you do it.
Sounds to me like when you say both that you want to learn discipline while also saying certain things are not your cup of tea, one of the areas of mentation you may want to work on is "the ability to experience, tolerate, and overcome discomfort". Discipline may even be described as that ability, in part.
Not saying you absolutely need to join any military service to get that, but there are few other circumstances where you have no real option of quitting once you've committed to a certain duration of obligation.
