I have had the same question. And I was brought up in many different protestant churches. Most of them taught essentials such as you'd find in Mere Christianity by C.S. Lewis. But they also divided over legalism, and dispensationalism, new thought metaphysics( word of faith movement).
I finally stumbled upon a radio program named the Bible Answer Man with Hank Hanegraaff. It was by his radio show that I finally was lead in a direction to seek out information and context especially.
In my own studies, encyclopedias are great for looking up manuscript names and evidence, as well as archaeology.
For gaining context a book named ' A Popular Survey of the Old Testament' - by Norman L. Geisler very helpfull.
For Eschatology – Revelation, Four Views, a Parallel Commentary by Steve Gregg.
Also the Popular Survey has some textual criticism. Having different versions of the Bible is nice for that too.
A concordance will help with looking up certain words and gaining definition and grammar on the text as well as tell you what language it was in and help to do cross references for further study.
And seriously consider using biblehub.com.
It's nice, many versions of the Bible to read. My personal favorite isn't on there and that is the New International Readers Version– which is basic reading in today's language–it is part 'word for word' and part ' thought for thought'.
And be sure to check out the lexicon on biblehub.com as it is a nice way to see the Hebrew word, or greek word etc…and helps study that.
And there are books to help you study,look up inductive reasoning a how to. Videos of Dr. Walter Martin on youtube aren't bad.
Pick a subject yourself, from the bible, get the context, do cross references, word study, look up any known archaeology of it…maybe like something on King Hezekiah. You can learn many things without even considering doctrine, but can help you to eventually test all things, hold fast to that which is good. Best of luck.
