Well, to be blunt that image seems pretty bad for what you are trying to do.
What’s up with the overlayed pattern? Is that a flyscreen?
I expect full automization may not be a realistic option at current, but a Layer Mask based on the green Channel and a very plain Layer Mask for the horizone should provide a fairly decent basis.
I had to recreate my attempt at adding clouds to the sky of a black and white image. Exactly what you see below is a little different than what I saw yesterday when I was working on this photo. This first screen shot is what I started working with. Not quite all of the layers are visible in the layers panel. There's a B&W layer at the top of the stack.
The next screen shot shows my request to add a few high-level cirrus clouds to a portion of the sky.
And here is the resulting fill:
This is somewhat different from many of the results I received yesterday, but it still illustrates the problem. First the clouds are cumulus and not cirrus and they are not along the top of the image. They fill about 80% of the selected area. Second, the Generative Fill added more mountains above the ones that existed before the fill was performed and are now blocking some of the sky. The ones added today are a bit more consistent with the real mountains in that location, while yesterday's were jagged, rocky peaks. Third, there was a strange object added to the top of the outhouse and the lettering on the sign over the door that said "Shown by Appointment Only" has been changed to something that is not recognizable. The outhouse was not in the selected area to be filled. I will add that the instructions I gave to Generative Fill for this example are not exactly the same as what I was telling it to do in yesterday's attempt, but the general nature of what I was asking for is the same. The other Generative Fill layers you see in the layer stack worked quite well to remove things that I did not want in the image. For those Generative Fills I did not give instructions for what I wanted. I just selected the area I wanted "replaced" then clicked on the Generate button and let it do its thing.
I'd appreciate any thought you might have about the way I'm trying to give instructions or whether I'm expecting the tool to do more than it's currently capable of doing.

@Bill Junk this might be too specific for the AI at this time. A better solution may be to use Sky Replacement. There you can either use existing images or upload your own sky images to use. This was an out of the box somewhat Cirrus looking cloud formation:
Third, there was a strange object added to the top of the outhouse and the lettering on the sign over the door that said "Shown by Appointment Only" has been changed to something that is not recognizable.
You can still edit the Layer Mask to hide unintended elements.
@Bill Junk make a selection approximate to the sky area. Then create a blank layer and hide the original image layers. Generate your prompt (this is "whispy clouds")
Then make a selection of your original sky area and use that to apply a new mask to the generated layer:
You can shift the edge using Select and Mask to contract/expand the area to remove fringing.
I haven't figured out how to do that with a mask on a Generative Fill layer. Using a brush to remove some of the mask didn't seem to work. I'm probably doing something wrong, but have no idea what.
I ended up using the Sky Replacement feature which let me select a reasonable sky for this image just to make the sky more interesting since the original color image had a blue sky with no clouds. Then I was able to correct an artifact resulting from something I removed with a Generative Fill layer. I applied a Brightness/Contrast layer as a Clipping Mask applied to another Generative Fill to get things looking smooth and continuous. Likely the hard way to do it but it works and I'm satisifed. Although I've been working with Photoshop for many years there's so much more I need to learn!
As far as a comment I made about trying to retain image integrity, there are times that I think it is important even when it's not related to image use in commercial settings. This image was a case where I was willing to let artistic creativity be the guide, rather than showing the scene exactly as it was originally photographed. There certainly are a few people who would know that the image has been doctored, but they are not likely to ever see the final one. Here's the original color image followed by the "new" black and white artistically creative image. Thanks for all the helpful suggestions. For anyone interested this photo was taken in Silver City, Idaho.
