It’s critical to note that not all paths/forms of meditation involve climbing rungs of a ladder or really any notion of a path whatsoever.
The practice of sitting is only for the purpose of training the mind to focus, which helps some people reach the “non-dual” state more effectively.
For example, the Dzogchen approach relies more on directly pointing out aspects of experience in a way that brings the listener more directly into contact with the current moment/unfolding experience and towards the same state that “ladder” meditation approaches aim to reach.
Many of the modern western teachers have gravitated to a more direct approach as well because it’s more palatable to the audience here (and frankly, far more practical and immediately useful).
Mentioning this because the perception that there’s a steep and long journey ahead is not necessary, and has turned plenty of interested people away from the idea of trying.
With all of that said, I haven’t explored Taoism, and it sounds interesting.
