Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Your attitude to exercise caution in reading material is correct. The great scholar and well-known Tabi’ie, Muhammed ibn Sireen Rahimahullah mentioned: 
إِنَّ هَذَا الْعِلْمَ دِينٌ، فَانْظُرُوا عَمَّنْ تَأْخُذُونَ دِينَكُمْ 
Verily this knowledge (the knowledge of Islam) is (your) religion; so look from who you are taking your religion.
Hereunder are a few good reads on the topics you mentioned:

The above-mentioned website contains many informative books and articles which primarily deal with misconceptions surrounding the Islamic history of the era of the Rightly Guided Caliphs and beyond. Attached below is an excerpt from the homepage of the website:
“The doctrinal history of Islam has not been without challenges. Attempts to part with orthodoxy and institutionalize innovation arose in the earliest period and continue in various forms up to the present day. The rise and spread of heterodoxy found fertile grounds in the vacuums of ignorance to which some societies occasionally tend to fall prey. Given such circumstances, the distortion of history and creed, combined with the fabrication of alternative narratives and meta-narratives, went a long way to entrench deviation. 
While many heterodoxies withered and disappeared with the passage of time, some managed to cling to existence and reinvigorate themselves whenever opportunity presented itself. In response thereto arose a scholarly tradition dedicated to the defence and vindication of truth. This website represents a continuation of that tradition.”
