If history is any example we already know congress won't do much unless it involves spending money. We saw that with the republicans expanding ICE funding instead of making careful country wide immigration reforms in collaboration with state governments who are needed for proper enforcement. Most likely if/when the democrats win we'll see them fund a new flashy anti-corruption agency, which gets added on top of the other 400+ federal agencies who already have multiple overlapping responsibilities.
And that doesn't work all that well if SCOTUS and POTUS work to just nullify said policy, as they did with things like the Voting Rights Act, the Clean Air Act, etc.
See, for example, Biden's attempt to forgive student loans (despite legislation permitting it) versus Trump's green light to try and wipe out the entire (Congressionally established) agency.
Best way to avoid this is having a competent congress, one that actually responds to public concerns so it's not forced upon the president. Which is always the root cause of all of this bad policy from the WH getting shut down by courts or risky incomplete policy being ignored by the courts for the greater good (like abortion rights never becoming a hard law through congress).
And to give equal time to the Dems: I believe that Dem leadership is fully corrupt as well, albeit in a more genteel fashion: they cater to the needs of the corporate elite, the moneyed class, etc and will never betray them by actively supporting worker's rights. I think most Dem pols are less corrupt, but the need for bribery, oops, I mean campaign financing, forces them into the difficult choice of staying in office or hewing to their values.
