What resources would you recommend to read if you were just leaving the church?

I’ve left the church a few months ago. I’ve learned a lot about some of the early history of Christianity and some about the SDA church. However, I don’t know much and feel like I need to learn as much about I can as fast as I can.

Do you have any advice on what to study, what materials to read or watch, what SDA doctrine/history is the important to unlearn or know?
