I would leave them alone. Just make sure they are clean. Since this is a rental, if what you try doesnt work out well, you have just made things worse, and that may anger your landlord. Let them decide, once you decide to move, since they probably know where they were purchased from, and the brand of cabinets, and the exact color. How did you get oil spots all over that you needed to rub that hard. I have never had oil on a cabinet. Food spills, yes, but, never oil. In any case, it may not even be your fault, it may be a defect in the cabinet finish itself. Best to leave for landlords to deal with.

I never have any problems posting pictures...! I never take pictures with a phone camera - only a real digital camera. I’ve seen people say they’re having problems with the up-side-down (or sideways) orientation when the photo was taken with a phone.... When I export photos from the camera software to a file for posting here, I save them as relatively small .jpg files so the file size is not large. I think that all helps with the posting here, particularly the smallish file size I think.

I can try to help. If you have pictures saved on your computer and want to add them to a posting, click on the photo icon just below where you are typing. That should bring you to your photo library. Select the picture you want and open it. That will insert it into your text. The picture will, at first, appear a little hazy. Wait until it brightens up before hitting submit and that should do it. Maybe someone else has a better step by step process for you. Good luck. Edited to add: I was typing at the same time as Lala. Hopefully, between the 2 of us, you'll figure it out.

We have used natural stone on raised portions of round spas. We don't use any of the pre-fab sheets as you mentioned. We use real, natural stone. It's a bit tedious, but each stone would have to be cut to conform to the spa radius. We have always run the stone down below the water line. Never stacked over the perimeter tile shown in the second pic. It's a better look. Here's 2 projects we did about 15+ years ago that have the natural stone on the exterior. Pics are way before cell phone cameras. So sorry for not being super clear. My client's moved out some time ago so I have no recent photos. This may give you some ideas. First one is Pennsylvania Bluestone. Second one was a variegated bluestone, but with more browns and tans.
