If you want to continue to use your sandpaper to 5000 (I assume this is P5000)..
The next logical progression would be a set of 3K/5K. If you are just going for appearance.
For more utility, as in sharpness, edge refinement, and to get away from the sandpaper, maybe a 1K/3k.
I know that Bob has recommended 800/3K, but that seems a pretty big jump to me. I have not tried it though, so this is conjecture. You do have the ceramics, so going back to the Chosera 1K, after using the Ceramics, for refining the reflectivity of the edge should be sufficient. This should also reduce the amount of work you need to do at 3K.
The thing is, this is difficult, the answer as always could be “it depends”. Maybe a set of 5K/10K would work after doing what you already are doing. For myself, I would have to just try it. The 5K/10K will also be the most expensive option. I can tell you that the “mirror” starts to really happen with the 10K Chosera.
I must say though, I use the 1K and 3K stones much more often that I do the 5K/10K. The latter are used only for maybe 20% of the knives that I sharpen. I would probably go with the former if I could buy just one set. You can always add the others down the road if you find your feet still sticking out of the rabbit hole …

BTW
Keep in mind that P5000 paper is (should be if it is P5000) rated as having 5 micron abrasive. (where did you get P5000 paper??) The 3K Chosera is rated at 4 microns. Beyond that though, and maybe more important in your case (looking for “pretty”) the chosera will give you more polish and certainly fewer left over scratches than any abrasive paper in that grit range.
BTW, when I first got my WEPS, I used sand papers and followed them by the 3M lapping films down to sub-micron grit. I got some nice edges, but it was a hassle. If you can get to where you are using just stones, it will make things much easier for you.
