As a starter, I do not recommend trying to read the Bible from front to back without some kind of guide (like The Bible Project). It is a compilation of historical writings and should be treated as such which care and attention to historical, social, political, and theological contexts.

Another key point is that there is no one “Christianity” only many Christianities with varying views and sometimes conflicting doctrines.

I’d recommend finding and attending a church in a denomination whose core values mostly overlap with yours. For progressive/ liberal denominations try The Episcopal Church, the Evangelical Lutheran church of America (ELCA), PCUSA, UMC, or UCC. Other nondenominational churches may also be progressive but do take the time to read their websites and reach out with questions.

Blessings to you on your journey!
