Premiere Pro's effect panel is missing critical information on the effects.
Some note if they are supporting 32bit float. But the reality is that many more than shown actually do. And the ones that don't you have to figure out via testing.
It would be nice if all effects would note what their operating depth is just like in After Effects!
With blurs for example, Premiere's Camera Blur is 8int or 16int but Directional Blur 32float.
