f the final checkpoint cannot be cancelled, can we bring it forward to start
upon completion of all tasks?

I'm afraid it's not possible at the moment, but would be a valid feature
request.
I'm not sure how helpful is this, but you can also manually trigger checkpoints:
https://nightlies.apache.org/flink/flink-docs-release-1.17/docs/ops/rest_api/#jobs-jobid-checkpoints-1
Alternatively, you can also disable checkpoints with finished tasks. If your
sources are finishing more or less all at once, the only thing you are
sacrificing is exactly-once semantic (like committing transactions to Kafka).
But you could still use Kafka sink with at-least-once semantic.
