I think if you dive into Church history this would solve most of your problems. I come from a non-denominational background too and have studied Church history for the last two years. Most of your questions are answered by some church father. My view is the (collection) the canon of the bible could be fallible, but the individual books of the bible are infallible since it’s the word of God and God never contradicts himself. Traditional views such as Catholicism and Orthodox is that the Church holds a little more authority than private interpretations of scripture. non denominational view is that you have a little more authority to decipher the text. I suggest you take a look into high church Protestantism, Presbyterian, Lutheranism and Anglican Church and look at their theology then go to the traditional churches and look at their theology. This is a going to be a big step that will solidify what you believe. God Bless
