I was also wondering about the tubes for new pilings, why are they
better than an augered hole with a small 2×4 leveling form at the top

It's not a matter of locking the concrete in the soil. It's preventing
frost from heaving the pier. A smooth surface reduces this chance
provided the base is below the frost line.
