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):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   6:              APFS Snapshot ⁨com.apple.os.update-...⁩ 15.2 GB    disk2s8s1



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!)

MacBook Pro 15″, macOS 10.13

You will probably need to start over completely.

Boot into Internet Recovery and start Disk Utility.

From the View popup menu, select Show All Devices.

Select the Device named, "APPLE SSD SM1024G Media"

Click the Erase button and use GUID Partition Map, APFS format.

You can name it anything you like.


Once complete, Quit Disk Utility and Reinstall macOS.

When that completes and runs the Setup Assistant, choose to migrate you user data from your backup.

When that is done, you can reinstall BOOTCAMP. I have no experience with BOOTCAMP, so I couldn't tell you if something you did with that caused the odd partitioning of your drive.
