"Base" scenes and Addressable Scene

Hi,
I currently have my own streaming system that use LoadSceneAsync (additive).
I basically have a world scene with interactive stuff where all the small static chunks are loaded.
Is using addressable for the static chunks going to improve my performance?
Can I use old style scenes and addressable scene in the same project?
If I load a new scene (single, not additive) are all the loaded addressable unloaded?

I don’t need remote/cloud loadinf. Everything need to be local/in the build

Also: are addressable fully working on console?
