I think one should definitely engage in multiple types of meditation rather than just relying on the traditional idea of sitting quietly with eyes closed. Different body types require different techniques, and a contrast of experiences can really help in triangulating, as well as increasing efficiency too.

Confrontational/Productive Thinking. Being introspective and teasing apart thought processes, past traumas and history, really examining critically why you thought or did something, where motivation comes from, what thought is etc.

Walking meditation is great, it allows the body to do something other than constantly nagging the mind about how numb your bum is getting sitting on the carpet. Natural surroundings require no dynamic attention - we're wired for it, we feel it succinctly. Look up 'Attention Restoration Theory'. My most productive introspection happens in my local park.

Lying meditation (corpse pose). There is a propensity to have visionary experiences lying down. I've had OBE's this way, seen through the roof of my house to the star lit sky, two DMT style experiences, lots of weirdness. There is definitely something to maintaining your awareness whilst allowing the body to fall asleep in the horizontal position; astral projection makes use of this technique. Which leads to,

Dream meditation. So powerful. Lucid dreaming being the starting point, becoming aware within the dream with the same clarity as you have right now. Learning to face fears, manipulate the dream, and pose questions - incidentally this made me realize there is a sort of inner guru, higher self, superior aspect of yourself, because it would literally drag me and show me an answer when I prostrated enough.

Being intently focused on the 'I am' seems to be the key to the door, through the different types of meditation. I find great resonance with the writings of Nisargadatta Maharaj and Ramana Maharshi in this respect.
