Looking for ways to help myself and team improve on general development practices and better software design

Some thoughts have included a kind of book club between us, picking some chapter from “Clean Code” and making sure we all read it and discuss how we could apply it to our work, but I am interested in any suggestions that could be a little more engaging/fun for everyone. Any tech leads out there that have struggled with this/what did you try or come up with? What worked, what didn’t, etc. Thanks and happy friday!!
