SCOTUS should hear the cases about Obama’s eligibility, subpoena all the records, and if it is found that he is not eligible he should be judicially disabled from “acting as President” as per the 20th Amendment. Joe Biden should immediately become “acting President” and be impeached for treason. Nancy Pelosi and all the other Congress-critters who knew Obama was ineligible should be arrested immediately for treason, after which impeachment hearings should be held for Joe Biden - with the one or two Senators who aren’t in jail.
That's an ambitious agenda. I doubt that our system is going to fully satisfy you in this case.
But, the future will bring other issues and challenges.
