I've also installed libinput-gestures and I'm using it in a GNOME 3.28.2 Xorg session (with "natural" scrolling disabled) on a MBP 11,1 with the configuration below. I feel this is pretty close to a macOS experience.

# Move to next/prev workspace

gesture swipe down 4 _internal ws_up

gesture swipe up 4 _internal ws_down

# Browser go forward/back

gesture swipe right xdotool key alt+Right

gesture swipe left xdotool key alt+Left

# Toggle Activities overview

gesture swipe up 3 xdotool key super+s

gesture swipe down 3 xdotool key super+s

# Zoom in/out (works in e.g. Firefox, Chromium, Terminal)

gesture pinch in xdotool key ctrl+minus

gesture pinch out xdotool key ctrl+plus
