Begin with al Usul ath Thalathah, al Qawaid al Arba, Kitab at Tawhid and Kashf ash Shubuhat, then al Aqidah al Wasitiyyah, which are the books the scholars named for exactly this, and the list changes with the level of the student. As for what comes at you on social media, do not sit with a doubt, take it to a scholar until it is answered.
