My question is, what is the benefit of digging a big hole, filling it with concrete and putting a concrete pier in it? I understand that it will be quite stable and free from any vibration from the ground but does it really offer much over putting a decent footing down and placing a tripod there instead?

Years ago I was in a similar position
I just used a 6' x 300mm dia. treated post
drilled and installed threaded rod on top
burried 3' in the ground.
"
Shovel about 3-4 inches of dirt around the bottom of the hole and tamp that dirt around the post you should not have to tamp it very hard since there are only a few inches of dirt to tamp. Level the post. add 3-4 inches more dirt, tamp it, and level the post again. Continue until the hole around the post is filled to the ground level of the post"
I was vibration free
and removable
