Julia, there is no single setting to recommend for NR in lightroom. Every ISO setting requires different NR, and it is different for each camera model, and different for images depending on the content. Basic NR as applied in camera or DPP, or Lightroom trades off loss of detail for reduction of noise, there are more advanced ways to do it that work around that issue by selectively applying NR.
Cameras typically add a lot of NR for jpeg images in the default settings, but they allow the user to use less, or even more if desired.
Lightroom has a brush that allows you to paint the area where noise is a issue, and then adjust NR for that area only. Thus, you can apply light NR to areas that do not need it, and more to areas that do.
I looked at the raw and jpeg images, the jpeg has a huge amount of NR, with sharpening added back in. I did not particularly care for it, but it was acceptable. In Lightroom, there are so many settings and combinations of settings, it is not just the noise reduction and the sharpening that is involved.
Here is my try to come close to your jpeg image. Its different, of course, you will never be able to match it exactly. Canon DPP comes close because they use the same basic software in DPP as in the camera.
In Lightroom 5.5
First, set the camera calibration. I used camera standard, and it was closest to your jpeg for color, contrast, and lighting.
Then, I turned on lens corrections, it found a Sigma 18-200mm lens.
Next, I set sharpening to 48, radius 0.5, detail 11
Then luminance 39, Detail 11, contrast 0
Color 9, detail 8, smoothness 37.
Finally, I set clarity to +15 in order to add contrast at the edges of the leaves. That makes a image appear to be sharper, but don't over do it.
I also processed it in DXO Pro Elite using the Prime NR setting. The result was splotchy and ugly on the dark leaves, but that is also a personal preference.
Basically, it boils down to personal preference, and learning what each of the controls does to a image.
Once you have a image looking good to you, then save the settings in Lightroom for that ISO, and it will be applied to every image shot at that ISO with that camera that you import from then on. You can also reprocess already imported images. Treat it as a starting point.
