realise this is a fairly old question but people have started commenting on it.
in my experience people are generally called to a particular spiritual path or practice at some point, it sounds like you haven’t experienced this quite yet.
Forcing spirituality isn’t something that works deep down. Your best place is to start with yourself meditating.
in my opinion discursive mediation is the best way (I’ll add a link)
I would start by focusing on each of the following questions over a period of time during your meditation. You could have a schedule of a daily 10 min meditation
week 1
why do I feel I want to start exploring spirituality?
week 2
what do I hope to get from my spiritual path?
week 3
do I want to follow a solitary spiritual path or be part of a group?
week 4
How do I feel about following a path which might lead to the dissolution of everything I think I know about myself?
Week 5
what changes do I hope I will produce from my spiritual practice
week 6
Do I want to follow a path with concepts familiar to the west or east? (This is a big one, you have only listed eastern spiritual practices - this is common and largely as a result of marketing. The West had some incredible spiritual practices and paths which, because they include concepts and language more familiar in the west often allow individuals to go much deeper into a practice)
Keep a journal of everything that comes up during those meditations.
Then start reading (primarily this will be driven by the answer to your last question) But your spiritual path has to come from within.
