In regards to screen time management and as a tech enthusiast dad of two kids--I have learned that simple low tech solutions work much better than most other more complicated methods. For example to limit screen time at night... we have a rule that all of the kid's devices need to be charged over night downstairs in the kitchen. I have a charging station setup in the kitchen for all their devices.
Also during the week devices are only allowed upstairs for homework use only.
