Had a very similar experience as yours and have arrived more or less on the same insight.
The Meditation Industry has made more noise in an already complex space. An attempt to oversimplify the topic for the purpose of commodification makes it worse.
For most part I also had been seeking a plug and play solution. Then I realised I just have to take a nose dive in the pitch black darkness to figure stuff out on my own. “Meditation” means different things to different people. Everyone’s internal make up is different and I feel exploring and finding your own ground is the only way to go about.
This discussion needs to be more nuanced and I could be wrong but that’s what I feel at the moment.
