I'm now on i3 (actually Sway), but when I was still using KDE Plasma, I extensively used the "quick tile" global shortcuts for KWin. They're not all bound by default, but you can set them up in System Settings (Global Shortcuts > KWin). I had it set up so that Win+S maximizes the current window (which by itself is quirky), and then every key around S is for a quick tile. For example, Win+Q moves the current window to the upper left quadrant. Win+D has the window occupy the right half of the screen, and so forth.

The only thing that I do miss from KDE times is the full KDE Connect integration. I have kdeconnectd running through some clever trickery, and the sshfs and MPRIS integrations work fine, but e.g. clipboard sharing doesn't work with Sway yet.
