I think there are several way of handling shots like this. I might try another but can’t get macrofusion to work. With that I would produce 3 different exposures from the raw file and blend them. The same thing can be done in the gimp with layers and masks etc. It’s hard to predict the result via macrofusion so in some ways GIMP is better but it takes longer.
I started off with a full sized flat image from the raw file via rawtherapee.

I recollect briefly using tone mapping.
I then switched to Fotoxx to use it’s tone mapping. It has a curve that controls what contrast levels are tone mapped. Heavy sharpening first using a 5 pixel rad on the full sized image. Then tone mapping followed by selective curves work on the sky and land. This left a selection line on the high contrast boundaries. A blend brush has been added recently so I used that on the line. New tool and I think it could do neater job than this. Then reduction and the usual post reduction sharpening.
Lastly a bit more brightening in places using the gimp. The usual desaturated inverted layer in soft light mode but I also used curves on it so that mainly brightened dark areas.
At this point I would probably normally go through all of the steps again.
