Phew all this talk about DE’s and WM’s and no one mentioned the one and only that every one would be happy to use as their main driver.

Running Window Maker in Arch is easypeasy and is very stable and easy to backup.
Window Maker (https://windowmaker.org/) itself has been around since 1997. It is an X11 window manager originally designed to provide integration support for the GNUstep Desktop Environment, a free adaptation of Cocoa (formerly OpenStep).
WML’s user interface can bring you a productivity boost without the excessive GUI bloat of modern-day Linux desktop environments.
The window manager is loaded with features and speed. It is easy to configure. It is easy to use.
In theory, WML is not bent on providing an alternative to today’s leading graphical user interfaces, but it certainly can serve that purpose.
Big surprise! Window Maker Live really is worth trying. I was expecting the UI to be not much different than Xfce or Openbox, but it is much different. In fact, Window Maker’s UI has features galore, and the ability to configure and tweak seemingly without end.

All of the above relates to a Debian Based Live os which I have never tried, it may be a quick and easy way to see what WM is all about though.
Also in the article there is mention of workspaces which may be of interest to you,
Working With Spaces
A major advanced feature I did not expect to find is virtual workspaces. You can open as many virtual desktops as your system can handle with memory.
A rudimentary workplace switcher sits in the upper right corner of the computer screen. Move forward or backward by clicking the tiny right or left arrow within the workplace switcher icon.
Right-click on the title bar of any window to send that application window to another workspace. You easily can navigate among all workspaces without taking your fingers off the keys. Just press the Alt + number key to jump to that workspace.
I do use the feature and have set up my mouse wheel to swap workspaces.
