Yes, trigger (once=True) set to all streaming sources and it will treat as
a batch mode. Then you can use any scheduler (e.g airflow) to run it
whatever time window. With checkpointing, in the next run it will start
processing files from the last checkpoint.

You should include commons-pool2-2.9.0.jar and remove
spark-streaming-kafka-0-10_2.12-3.0.1.jar (unnecessary jar).

You need to make sure the delta-core_2.11-0.6.1. jar file in your
$SPARK_HOME/jars folder.

You could try Delta Lake or Apache Hudi for this use case.

To achieve exactly-once with foreachBatch in SS, you must have a checkpoint
enabled. In case of any exceptions or failures the spark SS job will get
restarted and the same batchID reprocessed again (for any data sources). To
avoid duplicates, you should have an external system to store and dedupe
File streaming in SS, you can try setting "maxFilesPerTrigger" per batch.
The forEachBatch is an action, the output is written to various sinks. Are
you doing any post transformation in forEachBatch?
