You can use desktops in Mission Control to maximize your efficiency and control the clutter on your desktop.
These Apple Support documents will get you started:

Use Mission Control on your Mac - Apple Support
If you assign an app to a specific space, the app will always open in that space.
First, create a desktop space for the app you want to assign.
• Press F3 to activate Mission Control. Then move the cursor to the plus ( + ) sign at the top-right corner of the screen. Click that to add a new desktop. Then click the newly added desktop thumbnail to select and move into the space.
• Next, assign your app to that desktop space. Click and hold the app’s icon in the Dock until the pop out menu appears. (You may need to first launch the app to see its icon in the Dock.) From the pop out menu, choose Options > Assign To > This Desktop.
• Now, every time you launch that app, it and its windows will open in that specific desktop.
Other desktop assignment options are:
• All Desktops: The app opens in every space.
• Desktop on Display [number]: The app opens in the current space on a specific display (if more than one display is available).
• None: The app opens in whichever space you’re using at the time.
Once you grasp this, and especially when combined with trackpad gestures, spaces and Mission Control become awesome productivity tools.
To delete desktops, activate Mission Control (F3). Then slide the mouse up and hover over the thumbnail of the desktop you wish to delete and click the X when it appears in the corner of that thumbnail.
The key to clarity and the successful use of desktops is the assignment of apps to spaces after creating them.
