Go to a library, ask the staff this question. They will help you more than we can.

The only advice I'll offer is start local. Focus on your State or Region first.

""The People's History of the United States" by Howard Zinn is excellent, and literally changed my life.

It’s not in any sort of order but if you like podcasts, there’s one I like called The Dollop. It’s two comedians, one does a researched deep dive into American history and then he writes a narrative for his friend and then they riff and make jokes which helps keep it entertaining. They cover big topics and people like presidents and also lesser known stories. It’s all over the place in terms of timeline but I think it does a good job of doing a deeper dive on topics that just get glossed over but you can also see the similar thought patterns between people hundreds of years ago and today that lead to the same stupid ideas and decisions.

If you get an interest in the Civil War, Sherman's memoirs are excellent.

Hamilton the musical. And what the other commenters are saying.

Textbooks.
