Having a Creality Ender 3 Pro. Have upgraded the mainboard to a new Silent mainboard. Installed this Extroduer and also have a glass bed. I also purchased another glass bed to exchange the scratched one.

What should I do about my problem? Is my only solution to buy a CR-Touch Sensor? How does the sensor even work? Will it also scratch it when I am not careful enough or is it user friendly and fully automated?

I don't have any other bed except the glas one for now. Should I rather purchase a flexible sheet for the bed instead of a glas bed?

If i understand correctly, your nozzle is too high still even with your Z at its lowest value? You should be able to follow these steps to adjust it lower (under "I've added a BLTouch, how do I set my Z-Offset"): https://marlin.crc.id.au/forum/t/ender-3-v2-frequently-asked-questions/17#heading--zoffset

I still use Z clickers instead of CR Touch. My lowest low with the clicker/lever makes the Nozzle stop below my bed. I could remove the glas bed to shrink my bed and maybe put a metal sheet on it or purchase a thin plate, but with the glas bed, the lowest Low I can get with all the 4 corners is not low enough for the nozzle to not touch the bed.

The steps are the same regardless of what you're using for a Z sensor. The only issue I see is if your limit sensor physically won't allow the gantry to move lower due to its mounting position otherwise it's a 'soft limit' set exclusively in the firmware (which the above steps allow you to reconfigure).
