Hello, The 18 never came with a touch option, only the standard 1920x1080 LCD.
The Raw screen is usually just the actual LCD panel. You will then have to remove your broken panel from the display assembly and fit the new display. The second option you listed sounds like it's the full display assembly without the hard LCD lid. Be very careful with the display cables as they can be fragile.
I've never removed the LCD panel on the 18 so I can't tell you how difficult it is. The 17 R1 is quite simple compared to the older M17x/M18x series as the panels.
