Ask HN: An Ideal Project Task Manager?

I am looking for a project task manager with the following features (example).

---

Tasks, Sub Tasks (Graph), Recurring Tasks

- Add notes related to task (TickTick).

- Assign tasks to users or vice versa (ClickUp).

- Automatic addition of tasks to calendar when date is mentioned (Taskade).

---

Organization

- Projects

- Lists

- Tags

- etc

* Multiple views for each task list (Taskade).

---

Time Tracking

- Recording, Manual Entry (Toggl)

- Reports (Toggl)

- Activity Log (optional)

---

Suggest applications that are file-based (offline usage) or self-hosted (open source), AND/OR that provide ANY of the requested features using CalDav (but remain file-based or self-hosted).

Please don't recommend single user linux command line * (like orgmode or taskwarrior).
