gnome + lightdm + screen lock

For those folks who aren't able to use GDM3 due to various reasons (say, this bug) and switched to LigthDM there is a command we can use to lock the screen(possibly it could work with other DM too, I haven't checked though) :

dm-tool lock

To make it more convenient go to settings -> Keyboard -> Scroll to the bottom -> Click "+" button -> Create new custom shortcut using the command above like this.

To use Super+L combination you probably have to reassign existing system Lock screen shortcut to some other combination.
