Thought this new website might be of interest to you:
One of its creators is Luke Muehlhauser who is the author of the Common Sense Atheism website which was a huge help to me during my deconversion (Luke doesn’t add new content anymore to that site but the archives are still available and there is a LOT there.)
I poked around the worldviewnaturalism.com site and it looks like a good resource. The main categories are readings, podcasts, videos, debates, and people. The readings cover topics such as seeking truth, self & free will, ethics & society, happiness & self-help, and meaning & spirituality. You could spend quite a bit of time on this site watching interviews and following links to podcasts and debates. There are links to almost 100 intellectuals with a naturalistic worldview (including links to their faculty, personal, and wikipedia pages).
Let me know if you find something particularly interesting or useful on the WorldviewNaturalism.com site!
