The normal procedure of a color correction is:
1. Basic correction
2. Apply LUTs
But if I apply the LUT after the basic correction, FCPX places the LUT in the inspector UNDER the color correction. Shouldn't it be the other way round? Do I have to switch color correction and LUT in the inspector? The result is definitely a different one.
Last but not least: Should I apply the "Sharpen" effect before or after the color correction?

depends on what one uses a LUT for…
By its origin, a LUT was used only to transfer a clip from one color-space to another, e.g. a CLOG to rec709.
In this meaning, a LUT has to be applied first.
Meanwhile… stands LUT not only for 'correction' but for grading too (you remember 'cross developing' with film); then, a LUT has indeed to be at the very end of the workflow, after balancing and correction…
sharpen… imho, you have to sharpen first… any 'correction' could blur, and sharpening a blurred pic makes no sense to me.
1. Resize by putting i.e. 2160 into a 1080 timeline. All pixels are mapped anew, sharpening may not be needed or at least can be judged with the right pixels.
2. Put a normalization LUT on an adjustment layer over the clips.
3. Denoise. Then don't render but uncheck the filter for better realtime performance. Toggle it on on paused playback for all further operations.
4. Primary and secondary CC, grading.
5. Sharpening. This actually introduces disproportionate edge contrast, it's an artifact, and you want it as the last step except for ...
6. Add grain. If you did the sharpening afterwards, you would predominantly sharpen the grain.
7. Put denoise on.
8. Render / export.
