Photographing Bobcats with Sony A7RIV.

I have not had the camera very long and am using an adapter and A-mount lenses. I switched from the A99II to mirrorless and have not replaced lenses.
It is a bit of a struggle to learn this camera. The giant sensor has led to a lot of unexpected noise compared to the A99ii or A7III my other two cameras.
These bobcats were seen in Golden Hills, California.
The photos are from quite a distance with a busy background so stylistically not typical for me.
Any tips for getting the most out of the A7RIV?
For the sake of showing what else I am doing with the camera I included a couple landscape photos taken with the same camera and lens(Sony 70-400 amount).
