You can install conky with:
sudo apt install conky-all
Here is the repository for the Conky Manager:
sudo add-apt-repository ppa:tomtomtom/conky-manager
sudo apt update && sudo apt install conky-manager
You can browse Pling or DeviantArt for premade conky scripts.
The manager helps a lot.
Conky-all package installs the needed mechanics to Run Conky, but it does not really offer Conky's, or a way of easily managing them.
I don't use wayland.
sudo add-apt-repository ppa:tomtomtom/conky-manager
sudo apt update && sudo apt install conky-manager
I got this tip from an answer from Aravisiano
The Guide is now updated.
Any other things I should add?
Maybe how to restore vertical workspaces with extensions (if possible? 
)
How did you get the stats (system, HD, wireless) on the desktop?
conky - though it require that you can edit its config files to get it decent.
not working in Zorin 17 beta, at least not for me, even when running from git
script
There is the Extension V-Shell for customizing the Overview. With that You can set up vertical Workspaces.
That is Arcmenu. Or what exactly dou You mean?
Zorin Pro also have 6 desktops.
What I seeing Gnome is very configurable.
I must sayed newest ubuntu is near the same what Zorin but Zorin have a more desktop.
In ubuntu don't working many things and snap package doing this system slowly.
