We used to track and plan this ahead in a shared weekly schedule, together with feature work and assignments.

Any good (agile) collaboration system supports this. We did this succesfully in Azure DevOps and GitLab, for example.

That makes sense.

Did it still feel lightweight enough for very small, administrative routine tasks?

Yes, something like "Update soon to be expired SSL certificates" as a task with a deadline in the weekly planning.

The ops team then could assign the task to themselves whenever they were ready to execute. And as a manager it made tracking and follow up a lot easier.
