Can you move to another EU country without a job and receive benefits? If I recall correctly you need a job to be allowed to stay in another country even in EU. I think free movement even without employment is the main reason states can't enact too many benefits in US.

Europeans generally refer to "being on benefits" as unemployment allowance, and no, you cannot move from a poor European country to a rich one to get a higher standard of living unless you can work, or can be supported by someone who works. Certain kinds of social programs in the US have this property as well.

Americans often refer to medical care/insurance as a "benefit", which might be confusing here, but yes you absolutely can (as a European) move to another country without a job and still get medical care in the area you have just moved to.

Indeed, freedom of movement is one of the core principles of the EU
