You can configure a window resize hotkey. I use Win+(drag the window with right mouse) and it resizes it i the way you expect, moving the corner closest to the cursor. Left click would move the window instead of resizing.

This is by far my favorite way to resize and I don't know why it's not an industry standard.

The default config for this is to use Alt+(right-click drag) to resize and Alt+(left-click drag) to move.

I use this so much once I found it, this solved my frustration with the tiny resize border on the window itself.

This setting can be found in Settings > Window Manager Tweaks > Accessibility > Key used to grab and move windows: Alt
