The problem for rich book templates is that this template must have just the features what you need, nothing more, nothing less. This is very difficult to obtain in practice, when the election is a matter of taste. A rich class or book template could be useless for general use if everybody want to customize it. Even is you find the perfect template, soon or later you will notice that it was already used by a lot of people, so you will try to do something different to be an original guy, but then probably is better start painting on a blank canvas that correct that was already painted.
The exception are the academic environments, where the usually abhorrent taste from some academic authority that issued a standard style have priority, no matter your personal taste. Consequently, there a lot of thesis templates out there.
Another exception may be the highly specialized books, where the main priority is not the originality but the ease of writing the contents for a very defined format, that could be rich or not. An example are the cookbooks (see A cookbook in LaTeX?) that ideally could have a attractive format, and the opposite are the screenÂplays class that are intentionally (?) spartans.
Nonetheless, to the list of the standard book class, memoir, scrbook (Koma-Script), and tufte-book you can add the class bookest:
\documentclass[logo,guitgreen]{bookest}
\setlogooptions{width=2cm}
\usepackage{graphicx}
\usepackage{mwe} % for the example logo
\usepackage{blindtext} % tor the example text
\title{A Bookest Example}
\author{The Author (that's me)\\[1cm]
\inslogo{example-image-a}}
\begin{document}
\maketitle\thispagestyle{empty}
\tableofcontents
\Blinddocument
\end{document}
And octavo for pocketbooks:
\documentclass[titlepage]{octavo}
\usepackage{blindtext} % tor the example text
\title{An Octavo Example}
\author{The Author}
\begin{document}
\maketitle
\tableofcontents
\Blinddocument
\end{document}
And caesar_book, for (science) textbooks or theses. This class remember the tufte-book because the use of margins for notes, cites, tables and figures (the source code is in caesar_example.tex):
The easiest way to find any file in the TeX Distribution (if you know its name) is to use the kpsewhich program.
From the command line type:
kpsewhich article.cls
and it should return:
/usr/local/texlive/2016/texmf-dist/tex/latex/base/article.cls
on a TeX Live system.
Depending on your OS, you may be able to open the file directly. On a Mac, e.g. I can type
open `kpsewhich article.cls`
and the file will open in my normal TeX editor. (The back ticks pass the output of the command within the back ticks to the open command.) The equivalent Linux command is xdg-open I believe. I have no idea if an equivalent command exists in Windows.
