The problem with term limits for the Court is that it would require a Constitutional Amendment. And in the current environment it would be impossible to get an amendment through. One party operates on a political platform of spite, and now that Nancy Pelosi has come out in favor of it there is zero chance of an amendment getting enough support to happen.
Expansion is a possibility, though, because it's well established that the size of the Court is set by Congress. If Democrats control both Houses and the Presidency, it may be worth nuking the Filibuster for. Only after expanding the the Court do you go to Republicans and say "Do you want to work with us on an amendment for term limits for Justices, or do you want Joe Biden to nominate 4 judges to life terms all at once?"
AFAIK, the Constitution does not state that Supreme Court Justices have life terms. It is vague and has been interpreted to maybe mean life terms but it doesn't explicitly say that.
