Also not my specialty, but I did a lot of Conquest-era history during my undergraduate, so I know a bit of the historiography.
If you're interested in the Mexican example, Broken Spears: The Aztec Account of the Conquest of Mexico might be what you're looking for. It comprises translations of Nahuatl-language accounts of the Spanish Conquest. Here's a link to a short review for more information.
The book Broken Spears: An Aztec account of the Conquest is good on the pre-Columbian side of things.
Unfortunately there's not a lot of info about the Toltecs due to them being very ancient and there not being a writing system present when they existed.
But what I would HIGHLY recommend is two book that cover the conquest of the Aztecs by the Spanish. One is called The Broken Spears and is an amalgam of interviews with Aztecs in ancient times and excerpts from codexes that they wrote about their side of things. https://www.amazon.com/Broken-Spears-Account-Conquest-Mexico/dp/080705500X
The other one is called The Conquest of New Spain written by one of Cortez's men who took part in all of the battles with the Aztecs and somehow lived to tell the tale. https://www.amazon.com/Conquest-New-Spain-Penguin-Classics/dp/0140441239
Now, what's really fascinating about these two books are that they cover pretty much the same subject matter, that is the events of the war around 1503ish. You get to hear what the Spanish thought, and you get to hear what the Aztecs thought, and it's very fascinating. It's one of the few times that totally alien yet developed cultures have come together unexpectedly and with so much drama. You get to hear a ton about meso-American and Aztec life in general: their names, foods, clothing styles, societal systems, education, government, home life, religion, philosophies, hopes, fears, etc.
I just gave you several. https://www.amazon.com/Broken-Spears-Account-Conquest-Mexico/dp/080705500X
Acedemia.eu also has a lot of good papers if you’re interested in specific subjects.
Michael D Coe has a lot of good work as well.
Florentine Codex of course.
