And the winning de-noise app is.....

I shot this photo at dusk today with an ISO setting (auto) at 12,800. There's a good amount of grain in the image. With all the email adds this time of year promoting image editing software, I'm at a point that depending on what works best for me I might just spring for a denoise plug-in for LR, PS or just a stand-alone software.
So, with the attached image I would like to see what you can do to it using your denoise software/app to help me with my decision from what software works best for you and will possibly work for me.
I brought the image (RAW) into LR, cropped it and applied a little contrast, highlights and shadows adjustments. No sharpness, or noise reduction.
The camera and lens I used for this image: Fujifilm X-T2 and 100-400mm lens.
Thanks
Rich

You have to post the original uncropped / unprocessed image. Your 1280x853 attachment is worthless for the purposes of your requested editing exercise.
More importantly, seek improvements in your exposure technique that entirely avoids subsequent processing exercises. We see a static subject shot at 1/125 sec at 100mm using f/6.4 and ISO-12800. Your OIS-enabled lens is rated to 5-stops. Even at 2-stops, you would expect this same focused image at 1/30 sec using the same aperture and focal length, but bringing the ISO down to around ISO-3200. You should experiment and determine you own level of support from the OIS, and whether going slower is still an option.

I have a few different choices of denoise tools. If I take one of my very high ISO noisy images there are a zillion (slight exaggeration) permutations of noise removal I can do.
Getting the odd result by working on your image from someone who may have not have even used their denoise software to its best possible ability will be of little value to you. Why not undertake your own testing, the majority of software has a trial period?

When comparing things it is typical to use complicated images... the plague of Webinars pointing out changes that can not be seen.
"I might just spring for a denoise plug-in for LR, PS or just a stand-alone software." Is the question.
Be scientific. Set your camera at high ISO to purposely produce noise, the image should be of a flat surface with a test pattern of black white and then on one side colored lines. Flat Black spray paint on a flat white surface would do well. Then with that noisy camera image do your testing on downloaded 30 day trial copies of the deNoise software.
Don't forget Topaz Gigapixel, it contains deNoise and sharpening as well as pixel increase.

Whilst 'being scientific' with a test as you suggest is an option, it's problem is that you are photographing something you never will under normal circumstances.
Defining what is acceptable to you in that case will be far more difficult than using something we commonly photograph and look at.

Great advice. I will definitely keep this in mind when shooting under less than favorable lighting conditions.
I deliberately took the photo realizing what the ISO would be and thinking that I would run it by the UHH folks to see what they suggest. The photo was cropped very slightly to remove the cars in the parking lot. I would think that my photo is representative, and sometimes even worse, of what most photographers are faced with when ending up with a grainy image due to high ISO. We've all been down this road before and continue to be faced with this issue. So, my question is, what tools work best for you during post processing in an attempt to rid the photo of noise but yet retaining edge sharpness. Thanks for commenting ~ Rich

Rich, the internet says the X-T2 is a 24MP sensor, so an image at 6000x4000 unprocessed would be the file needed for your proposed processing exercise. I'm not seeing any noise in this small attachment.
For Noise processing in LR, I've written some ideas on both noise and sharpening, two sides of the coin when editing in LR alone. You should consider if the ideas on using refined Noise processing in LR alone is sufficient.

Here's a photo I took a couple of days ago. Same conditions, dusk, low light, ISO 12,800 with the same camera and lens. I brought it into Lightroom, RAW, no adjustments and exported it at high JPG resolution.
I read and see so much about eliminating noise (grain) using various software that is out there today. Some of it looks amazing and almost too good to be true. I'm just reaching out to the group to apply whatever method they use to reduce grain in an image by using the image I've presented.
I much appreciate any and all suggestions and for taking the time to work the image.
Meanwhile I will look into what others have already suggested. Nothing ventured, nothing gained!

AI denoise does a very good job if the noise is extreme. Your posted photo doesn't have extreme noise, or even moderately bad noise, so basic denoise and sharpening tools are enough.
Lr's sharpening tool allows you to limit the sharpening to the edges and keep it away from the noise where it's at its most visible, which is in large, smooth areas that are devoid of fine detail. It's the Auto Masking slider that allows you to do that. To see what's being affected by that slider, hold down the Alt key when you operate it. You want any large smooth areas to show up as black.
I suspect that what you're seeing on the scarecrow's face is real life texture and not noise.

Again, this static scene shows a OIS-enabled lens and an unnecessarily fast shutter; and therefore, an unnecessarily high ISO. You keep asking about software -- in post -- where the root-cause is your image capture technique.
I see Capture One 21 Windows reported in the 'software' details of the EXIF. Consider a) if the 24MP RAW can be attached directly to UHH, or b) if the Fuji site provides a conversion software to dump the JPEG.
Here's a look at the Luminance noise of the details. I'm not seeing any color noise. But, I'd want to see the original RAW file, not the CO21 output. The links above for LR gives ideas on how to address the black specs (luminance noise) of this image, as well as adding sharpening to the details.

Alas, when I check the specs, I'm finding "No" in stabilization for this X-T2 model.

Hmmm... Some say yes, some say no. This is a quote from a Google search:-
One question that some photographers have is whether or not the X-T2 has IBIS (In-Body Image Stabilization). The answer is yes – the X-T2 does have IBIS.

I checked Fuji directly and failed to find a 'yes' answer. The DPReview explicitly says 'no'. So, I deferred to the lens capability in suggesting a slower shutter option.

This is from the Fuji site specification page:-
Image Stabilizer - Supported with OIS type lenses
So it looks like OIS only.
