I doubt there'll be anything in there that we don't already know or at least suspect, but it'll be an interesting case in how much Biden's DoJ is willing to kowtow to the precedent set by the Trump DoJ. I suspect not much.
From Politico: Judge orders release of DOJ memo justifying not prosecuting TrumpA federal judge has ordered the release of a key Justice Department memo supporting former Attorney William Barr’s conclusion that former President Donald Trump should not be prosecuted for obstruction of justice over episodes investigated by special counsel Robert Mueller.
U.S. District Court Judge Amy Berman Jackson issued that ruling in a withering opinion that accused Barr of being “disingenuous” when describing Mueller’s findings and found that the Justice Department was not candid with the court about the purpose and role of the 2019 memo prepared by Justice’s Office of Legal Counsel.
In response to a Freedom of Information Act lawsuit, Justice Department attorneys argued that the memo was part of the process of advising Barr on whether Trump should be prosecuted, but Jackson said the analysis consisted of a post hoc rationalization of a decision already made.

While it is unclear if it influenced her ruling, Jackson had a close-up view of one of the biggest firestorms of Barr's tenure as attorney general: his decision to overrule front-line prosecutors and effectively withdraw their recommendation of a seven-to-nine year sentence for President Donald Trump's longtime adviser Roger Stone on charges of lying to Congress and witness tampering. Jackson — who was the judge in Stone's trial — wasn't openly critical of Barr's move, but made clear in court that she believed it deviated from the administration's stated policy on sentencing matters.
