If I wipe out the storage device does it wipe out the volumes and container as well?
I ask because it looks like my Mac has two storage devices and a container. What is the most thorough way to wipe out my Mac?

I ran diskutil and noticed a bunch of extra volumes that I'd like to delete.
From what you posted from diskutil, none of them are "extra."
Everything on your Mac is as it should be.
Big Sur splits the drive into multiple volumes. The two main ones are the System volume (Mac HD) and the Data volume (Mac HD - Data).
Further, it creates a Preboot, VM, Recovery, and Update volume.
The com.apple.os.update.… volume is the Sealed snapshot of the boot volume (Mac HD). The Mac boots from that sealed snapshot which prevents any modification to the OS by anything.
What happens if I wipe everything out? If I plug a bootable Big Sur USB in safe mode will everything be restored? I'd like to start fresh.
You would completely wipe out everything, and then when you re-install, it will look exactly like it does now. You will not have changed a thing, but you will have wasted a lot of time. If it is an M1 Mac, you can possibly render it unusable until you take it to an Apple Store or use Apple Configurator on it from a second Mac.
Again, what you seek to do will not accomplish the goal you seek.

What is one trying to the achieved ?
Is there an issue wherein the computer is not functioning ? Is the computer Mal-functioning ?
Below is the Terminal to list all Volumes on this computer and looks much like yours.
So Suggest leaving the volumes alone as other Contributors have mentioned

Do not wipe out the Mac HD and the Mac HD - Data volumes or their devices. They both must be there for you to boot your Mac and have the needed User data and files. On your Mac outside of Disk Utility, you will only see it as one volume.
I ran diskutil and noticed a bunch of extra volumes that I'd like to delete. Basically I'd like to completely wipe out the Mac to install a fresh copy of the OS for a clean start. How would I do this? Will running Disk Utility in safe mode let me wipe out all my containers and volumes? I've never done this before.
Don't touch them. They are all needed for booting and running the Mac OS and your setup.

They are relevant, though a little dated.
I wanted to reinstall the OS because I was getting a bunch of kernal panics, beach balling and the fans would spin real hot. I wiped everything and reinstalled the OS from a flash drive and everything seems back to normal now.

You likely had an incompatible third-party kernel extension installed which was removed when you erased and reinstalled.
I ran diskutil list in Terminal and found all these volumes I'd like to wipe out and start fresh.

as already correctly stated, DON'T try to remove them. they are all required.
If I wipe out the storage device does it wipe out the volumes and container as well?
