Sorry, I don’t know of any good resources off the top of my head

Agnostic Theist

Or

Agnostic Atheist

Are what the majority of people are.

Agnostic makes the most sense because there is no “proof” a God or gods exists or doesn’t exist.

If I walk up to a Theist or Atheist and ask for “proof,” neither side will have any.

When you ask a Gnostic Theist that practices Christianity (but could be any religion). They will say that the Bible is “proof” and that they know that to be the truth. They claim to have the knowledge that their belief is correct.

A Gnostic Atheist doesn’t really exist. Because they would have to believe in some knowledge that is “proof” for their belief that no God or gods could ever exist. There is no knowledge out there that proves that.

It becomes a semantic battle of what do you call the God or gods and that “Anything is possible”

So you can assume anyone that calls themselves Atheist is an Agnostic Atheist.

As an example, no Atheist is going to lay down their life to die on a hill that no God or gods has ever existed. They believe that no God or gods existed, but they realize that the knowledge to prove it doesn’t exist yet.

A Gnostic Theist will die on the hill for what they believe because they truly believe that they have the knowledge to prove it.

Plato has a lot of good stuff to read up about religion

But unless you want to pick a religion and roll with it on faith, agnostic is what it is.

It’s nice to hope for a nice God or gods. That would make you Agnostic Theist.

But if you feel like a God or gods don’t exist then you’d just be Agnostic Atheist.

But to become religious, you’d have to read about all the different ones and see what speaks to you and decide yourself if you want to buy in or not.
