I've found a real interest in learning the somewhat "mundane" details of what everyday life in different places was like for its citizens. I'm interested in learning about what goods and services were most important to them, the types of religious and normal beliefs they had, what things were accepted and taboo, what games they played, what holidays or ceremonies were important to them, just anything like that. I'm not so interested in kings, battles and conquest, but what most people were doing with their everyday lives. I just really don't know what genre or category this falls under enough to find anything on my own targeting this with more specificity.
It may be weird to say it this way, but I'm really interested in how different civilizations and towns functioned more than what they are. So essentially a sort of "functionalist history" is the best way to describe what I'm interested in.
Thanks for any help with this. It took a lot of thought just to explain it this much, so I appreciate anyone who tries to answer (even if it's just how to be more specific with my questions next time).
Greenwood Press has actually published a Daily Life Through History series, with books focusing on daily life in specific periods/places. I think that their instalments on daily life in Egypt, the Hellenistic era, Nubia, and the Roman Empire are good as introductory works. Each has their strengths and weaknesses, and sometimes there are gaps in sourcing or overgeneralizations. Because of that, they are best used as a starting point and not the end all be all of scholarship.
That said, I think the Greenwood series is as comprehensive as can be expected while still being concise and accessible to general audiences. The series also includes books about the Americas, Africa, Asia and Europe through the Middle Ages all the way up to the modern era (although I don't know what experts think of these). The whole series is very accessible online through virtual libraries if you are so inclined.
Many works on daily life in Egypt do focus on particular individuals' lives which you mention you don't want, but they use this as an example from which they can paint a broad picture of what life in Egypt was like. This is also sometimes a consequence of how evidence comes down to modern historians. Sometimes archaeologists will find an archive of documents relating to a specific family or village over generations, and a book will be based around that evidence. For examples of these kinds of works, Koenraad Donker van Heel has written Mrs. Tsenhor and Djeky & Son: Doing business in ancient Egypt which are about "normal" people in ancient Egypt. Daily life in ancient Egypt: recreating Lahun by Kasia Maria Szpakowska is another good example.
Still others might focus on women's lives, or on life in specific cities to help narrow down the focus of the book. Depending on your interests, there's a lot to choose from!
Finally, the AskHistorians booklist does have a number of books focusing on daily life throughout history, but it's still a growing resource.
