How do I remove Moire patterns from defishing?

With the H100, you should be able to use the torch-addon an ml tools, so scunet&basicvsr++ are an option.
You should make sure to use lossless formats as intermediate otherwise you end up compressing compression artifacts and creating new compression artifacts,..

(but I just tried Hybrid, and found it better, but the Bob is not working to double frame rates, and I have to increase to 60, to get 30fps. it's not automatically set correctly.)

Then you are doing something wrong.
Hybrid can bob deinterlaced fine (assuming it knows it should bob and that the source is interlaced).
Hybrid also can interpolate to different frame rates.

If it didn't zoom in, it would cause the border to be exposed at 100%, because of the shaking and Rock Steady smooth out, so all frames are fitted to size, position, angle, etc., to make it look nice, without reflections or black borders. Simple cropping doesn't work.

Normally, stabilization should add black borders all around, then once crops those borders and if needed/wanted resizes the result. The last resize should be skipped. So the idea is not to do a simple crop, but deshake and then crop. So if for stabilization you loose XY pixels at each side your resolution is lowered by that.

We really need to know what we are doing, and would be better if the GPU was used. Max Conversion rate is about 5-6fps.

Hybrid too has tons of encoders and filters which support using the gpu.

I also use HandBreak for deinterlacing SD,

Personally, I wouldn't use handbrake at all in this process.

Hybrid is best in serious problems, and the steepest learning curve by far.

Yes, Hybrid assumes that the user knows what he is doing.
