Yep, Sonotube or the equivalent is the only way to go for short piers
(5'-15') or pad & piers. And you don't need to remove it - it eventually
just goes away.
They are amazingly strong and come in every diameter imaginable. Good
for elevated guy anchor posts. And subwoofer cabinets too!

Here’s how the big boys do piers…. Don’t need no wood.

Got to watch a 350 foot Rohn SS go up…
24x 24 foot hole, 40 yards of concrete. Pad and pier.
Each leg of the first section was 1100 pounds.
