A bit basic, but I've been using "FancyZones" [1] from Microsoft's PowerToys [2] (installable via winget) on my work machine.

It at least provides options to e.g. split the display into 3 zones, meaning I can keep my main window centered with a non-ludicrous width and I don't have to permanently look to one side.
