On macOS I use hammerspoon to define window positioning keyboard shortcuts. With my 4k monitor I can place windows in a 4x2 grid, or 4 columns (both similar layouts to my two-screen setup), or 3 columns, or left half / right half / middle half (with two narrow columns either side). On Linux I use i3wm, but I have not yet configured it for my 4k setup.
