hachareidy hoamity: you are translating sheker hachein incorrectly. It doesn’t mean that beauty isn’t worth anything – especially in a marriage, finding your spouse attractive is extremely important! Rather, it’s saying that a PERSON is not worthy of praise for being beautiful, as it’s not something they did themselves.
People love to quote the Mishna which says the girls used to say that on Tu B’Av and Yom Kippur when they’d come out and dance. They forget that it was said by girls who were not attractive, and were trying to attract a husband. In fact, the same Mishna says that the beautiful girls used to mention their beauty!
Chein is different than physical beauty. To say a husband should ignore physical appearance for the Yiras Hashem his wife has is just ignorant. The Gemara says that a husband should see his wife before they are married to be sure he finds her attractive.
