Personally, I found Kavita and Grimmory far too complex for my use and also very resources hungry. At the end CWA is just perfect for me. Still have to configure my kobo e-reader to use it directly and this will for sure be a game changer from my current solution which consist in converting epub to kepub with kepubify and then put it on a local webserver that I open through kobo web browser.
Calibre Web Automated is a completely different project. I am liking it so far.
Some people have also suggested Kavita.
