Here is a non-exclusive list of some values and practices I love in Judaism, or at least ones for which Judaism offers a strong support structure:
-Family ties, kibud av v'em, kibud zekenim:
There is a strong sense of community built out of family structure. I do believe that in the modern world, there can often be a lack of respect for parents, or a lack of cohesion in a family. Judaism tries to provide structures by which all of the above are supported. Families are brought together through the structure of chagim, Shabbat, smachot, etc; children are taught about familial responsibility, and obligations towards parents; we are taught laws about how to honor the elderly.
No, not the prude sense of it, nor the idea that women need to be forced to hide themselves in silly ways. But I certainly appreciate the value that more attention should be paid to a person's interior; that there is value and dignity to living with some sense of modesty; that some things should be kept special between a married couple. (Say what you will about hair coverings, but isn't it important and valuable that some things between a married couple be kept only for each other?)
Yes, I believe Orthodox Jews are, at least in a lot of circles, too insular--but that seems like the price paid for the benefits of a tight-knit community. And I do love being able to walk in a Jewish neighborhood on Shabbat and say "Shabbat Shalom" to strangers, and have a sort of instant bond.
There is something unparalleled about having a forced day off from mundane matters, when one must spend time with family and/or rest from the everyday rush (even if there can at times be frustrating sides that come along with it).
The notion that we live in an imperfect world, and it is our duty to fix it. When utilized correctly, what more inspiring mission could we have than that?
