My go-to resource is the NN Group (https://www.nngroup.com/). One of the most serious publication that tries to back up insights with actual data.

Then there are the publications from people in the industry that can be interesting, but that's case by case. You'll have better results for specific problems like building and maintaining a design system.

You also have the UX collective (http://uxdesign.cc/) but their articles are hit or miss. Good ones at least provide references for you to explore deeper.
