I don't think standalone is the problem. You described creating only one pool, so I think your problem is that you need at least one more pool and assign each job to a different pool.

FAIR scheduling is done across pools, anything within the same pool will run in FIFO mode anyway.

This is based on the documentation here: https://spark.apache.org/docs/latest/job-scheduling.html#default-behavior-of-pools
