Revisiting some of her testimony to the Senate Banking Committee in 2013 as her nomination to be the first Federal Reserve Chairwoman moved forward, there's some pretty good and solid defenses of her policy views (which were, at the time, considered a bit controversial, but in hindsight have looked remarkably smart). In her defense of easy-monetary policy, which former Republican Senator Bob Corker (TN) had called "elitist", she replied by noting that the low rate policy adopted by Bernanke in the wake of the 2008 crisis had also had the effect of stabilizing the recovery in the US housing market, and calling it "broadly beneficial" to all those who own homes. Indeed, even throughout the deep recession caused by the enduring Coronavirus Pandemic, the housing market has remained incredibly strong (and perhaps stronger than it was pre-pandemic, against conventional wisdom during downturns).
In that same committee meeting, she faced some actual grilling from Liz Warren, who argued that the Fed should have had foresight - saying the lack of lack of attention to regulatory and supervisory responsibilities lead to the financial meltdown in '07/'08. Yellen's response acknowledged the shortcomings of the past, and pushed her vision for tighter and more strict enforcement. She viewed goals such as reducing systemic risk in markets to be a top priority of a Fed under her supervision. She won over a skeptical Warren who concluded by saying that she hoped "very much" that Yellen would be confirmed, and that she would keep our markets & financial systems safe.
Her opening statement is worth a read, too, because it remains pretty damn relevant even 6 years later:

The confirmation battle wasn't necessarily a hard-fought one nor a slam dunk, but ultimately Yellen's appointment received 56 yays to 26 nays. It was the narrowest confirmation for a Fed Chairperson. By contrast, Jerome Powell's confirmation passed by a vote of 84-13. Pretty indicative of the two party system where each party plays by a different set of rules and each party is graded on separate curves of "reasonability". I do anticipate that Yellen's appointment may have some frictions getting passed. I really don't know how hard of a line McConnell plans to take on Biden appointments, and whether he'll try to hold the cabinet hostage or not. It's a scary proposition.
