Yes, it's fuzzy just because there doesn't seem to be a general widespread agreement on terminology, even among "experts", so that someone uses the word consciousness meaning something completely different than someone else. It seems that each time one wants to embark in a consciousness discussion, there should be a glossary preamble to specify definitions.
Regardless of the breadth of the spectrum of definitions, at the very bottom you find phenomenal consciousness. The given, undeniable fact that "it feels like something". We don't have a plausible avenue, not even in principle, to even start addressing this fact of existence, to the point that the most rational stance is to assume that it is fundamental in nature.
