Like many folks I know, I have struggled for years to find the best project planning tools. I’ve tried a whole bunch of them—Basecamp, Trello, Monday, Asana—and they all have their compromises. For the last few years, I have been using a tricked-out Google sheet that does exactly what I want it to do. Takes a little maintenance from time to time, but is super easy to use as a template from one project to the next with the change of two or three inputs. Happy enough with it that I have posted it for sharing. You should be able to make a copy to your own Google Docs from this one.
