As recommended by Power BI Documentation (https://learn.microsoft.com/en-us/power-query/dataflows/best-practices-developing-complex-dataflows), it's more efficient if you separate the ETL in different dataflows by having a staging dataflow and a transformation dataflow. By doing so you gain a lot in efficiency, but not much on administration. As you split ETL in many dataflows and datasets, by the time you have to set a individual schedule configuration for each dataflow/dataset that belongs to the lineage.
To make schedule administration easier, it would be nice if we could configurate a Refresh Chain, where you could select a specific dataflow/dataset, view it's refresh timeline. Then all dataflow/dataset dependency would be shown in a timeline graph.
It would also be nice if we could configure the refresh schedule of the first dataflow/dataset in lineage and the following dataflow/datasets would have a option to schedule a update "As soon as possible".
