Help with hard drive set up?

I recently did a clean reinstall of macOS Monetary and Windows Bootcamp. But I'm not sure if my Hard drive is set up correctly, as there are some oddities I have noticed:

Oddity 1: Disk Utility Oddity​

When I look at my hard drive in Disk Utility, there is a mystery partition called Container disk 1 and Container disk 2:

The container disk can only be erased, but not removed. I've Google around and lots of forums say that's normal. However, having 110GB taken up like that seems like a waste of space. Is it normal? Also, what is a snapshot drive?

There is also OSXRESEVRED. This is not a drive I made. I think it came when I did the Monterey install.

Oddity 2: Boot menu Oddity​

If I restart MacOS and hold down alt, the boot menu shows the following:

It's showing two windows drives, but I only have one. 

Also, the spinning icon spins continually.

In fact, when I select the Mac drive, the icon continues to spin:

Oddity 3: Boot Camp Oddity​

When I am in bootcamp and select "Restart in MacOs" it says "Could not locate OSX Boot Volume"

I am not sure if that means anything significant.

Terminal Output​

Here is how my drives look via terminal using the command: diskutil list internal

Code:

/dev/disk0 (internal, physical):

Is this all normal? If not, how do I go about fixing it?

I am happy to do a clean install, but how do I do it correctly, so I can wipe away all the mystery partitions? Also, do I select AFPS, Master Boot record, Apple partition Map. There's a lot of options, and I am not sure what is right (and I suspect that's how I got into this in the first place!)
