The 2nd version (your first RAW) edit seems the most natural to me.
It has a slight green cast. Thought that may be accurate with trees overhead out of frame.
Most people will probably prefer the original JPEG, because it's got lower black levels, and more color saturation. But it's just a little over done for my taste. Somewhere between that and your first edit would be the sweet spot I think.
The auto WB just looks wrong. I think it's overcompensating for the green cast, now it's too pink.
At these scaled down resolutions, we can't see the difference in noise reduction.
But at bright daylight ISO levels I doubt you need any. Maybe just a little color noise reduction if you'd like.
This is the JPG the camera generated.
This was my first RAW edit. Untouched white balance with increased saturation, vibrancy, and a little noise reduction.
This is the next RAW edit where I allowed an auto adjustment of the white balance (The lighting was 2pm in Beverly Hills, if that adds context) and actually used less noise reduction.
