What system of projects and tasks do you recommend for a small team?

Question

Project management

We are looking for a system of projects and tasks for a small distributed team.
Requirements:
1. Free for up to 7 people
2. Cloud solution
3. Not bulky interface
4. Availability of project templates (optional)
5. An important point for the director! The executor creates a task according to a template, the manager accepts or rejects it, and if the task is closed by the executor, the manager must see and control this.
6. Ideally, a calendar view like Gannt Pro or Asana.
What we tried and did not work: MS Project, Bitrix 24, Trello, Wrike, Megaplan
While we are sitting on WorkFlowSoft, but somehow everything is not right either.
