I am a bit lost in how I configured this all originally, new to Proxmox relatively. I deleted a container that had a large footprint but seemed to have gained nothing back?

Please edit your post to use code blocks. Also share lvs -a. To find used storage on local try this
Bash: 
apt install gdu
gdu /

Did you find anything interesting with gdu? Can you tell me which storage your CT used to use and where you check the free space and what you see?
Since the formatting in the first post is still pretty bad maybe you can share all of these again too just so I have all the context I need
Bash: 
df -hT
lsblk -o+FSTYPE
cat /etc/pve/storage.cfg
zfs list -rt all -o name,used,avail,refer,mountpoint,refquota,refreservation
local-lvm should have about 40% free space. Make sure to set up discard properly for thin-provisioned storage like that.
VM-Storage seems to use pure LVM rather than LVM-Thin. I'd move the disks on it to somewhere else and re-create that if possible.
There's also what looks to be a ZFS storage but I can't tell what you use it for and how.

If you want to drill down into the filesystem finding the biggest files and consumers, you can also use a recursively called
Code: 
du -h -d 1 <path>
.

du works like dh, but just for files and not for partitions.
Code: 
-h
activates human readable size units,
Code: 
-d 1
just gives you the information for the requested paths with the depth of 1.

gdu already does that in a interactive way. If you use du you should probably also combine it with sort.
