I use the tiling window manager i3 (https://i3wm.org/). When I log on, I'm greeted with a blank screen. Most of the time I have a fullscreen terminal or web browser, without even a title bar.
On my 4k work monitor I can actually take advantage of sophisticated tiling.
I used to use xmonad (another tiling WM), so my keybindings resemble what I'm used to from that.
I make heavy use of workspaces. i3 also allows me to rarely use the mouse/trackpoint.
