Reddit reviews Ethics from Sinai: A Wide-Ranging Commentary on Pirkei Avos (English, Hebrew, Aramaic and Aramaic Edition)

The following is a list of basic books that will help you get a good handle on traditional Judaism. All the books listed are broadly recognized as being reliable, and many are considered classics in their own right:

• A Maimonides Reader by Isadore Twersky. An excellent compilation of the writings of Maimonides covering almost all of the most basic concepts in Judaism.
  
  
• With Perfect Faith by Rabbi J. David Bleich. This is an excellent introduction to medieval Jewish philosophy, based on Maimonides' thirteen foundations. Includes extensive lengthy quotations from many major Jewish philosophers.
  
  
• Path of the Just by Rabbi Moshe Chaim Luzzatto. Classic description of the ideal spiritual Jewish life. The opening chapter is particularly important for understanding almost all of modern traditional Jewish thought.
  
  
• The Nineteen Letters by Rabbi Samson Raphael Hirsch. An classic overview of Jewish thought presented in the form of a correspondence between a young rabbi and a childhood companion who is questioning the purpose and validity of traditional Judaism.
  
  
• The Stone Chumash - A good one-volume translation of the Torah, with an extensive commentary based on traditional sources.
  
  
• Ethics from Sinai by Irving Bunim. An excellent, three-volume commentary on Pirkei Avos, the Talmudic tractate that deals with ethics.
  
  
• The World of Prayer by Rabbi Elie Munk. An excellent two-volume commentary on the Jewish prayers.

I don't know much about the others, but I really don't think Sam Harris is someone to try to gain wisdom from. His central thesis is just wrong and awful.

You should speak to as learned a Rabbi as you can find and ask to learn Pirkei Avot, and to go deeper with what's known as mussar. There are many books in this category, but probably the most famous and foundational is Mesillas Yesharim. It's quite an advanced text, but it is also very accessible on a simple level. I wouldn't recommend trying to learn it on your own, but if you are interested in starting with Pirkei Avot on your own, I've heard that this is a very good commentary for beginners.

It's obviously much easier to give a Jewish perspective on a specific issue than to provide you with sources for getting the Jewish perspective on everything, so if there's something in particular on your mind (or that you'd like sources or maybe even lectures to investigate further), you're welcome to ask and I can do my best.
