She said she was drawn to the character's potential for depth. Director Leigh Janiak suggested that Sink watch , such as Friday the 13th (1980) and Scream (1996), to prepare for the role. She did most of her own in the film. Sink's acting received critical praise; the Los Angeles Times commended her portrayal of Ziggy's emotions, attractions, and loyalties, and RogerEbert.com said that her "intense performance gets a great deal of volume" from a one-dimensional character. In the trilogy's third film, (2021), she played Ziggy and Constance.

The singer had been impressed by Sink's onscreen presence and emotivity in Stranger Things. Swift said that had Sink declined her offer, she would not have proceeded with making the film. Sink saw the role as an opportunity to "step out of being a kid on screen" and play a "more rounded and mature" character. The short received critical acclaim. Collider stated that Sink and O'Brien gave "vividly emotional performances" and told "an incredibly moving tale of love, power, gaslighting, and heartache".

Critics gave the season positive reviews, with Sink receiving acclaim.

Several publications expressed disappointment at her failure to gain a nomination for the Primetime Emmy Award for Outstanding Supporting Actress in a Drama Series for the season.

The film was met with mixed to negative reviews, but Sink's performance was met with critical praise and seen as a standout in the film. Sink later returned to Broadway, starring in the comedy play John Proctor is the Villain. Opening in April 2025, the play and her performance was met with critical acclaim. Christian Lewis of Variety wrote that Sink "gives a spellbinding performance as a girl who is deeply pained but shielded with thick armor: She's smart but underestimated, and ready to harness her rage against the patriarchy." The role earned her a nomination for the Tony Award for Best Actress in a Play. In March 2025, Sink was cast in the Marvel Cinematic Universe film (2026) in an undisclosed role. The same month, she fronted a recycled nylon campaign by Prada alongside Benedict Cumberbatch.

Sink has gone on record to state that she prioritizes her privacy and chooses to not publicly discuss details of her private life. In an interview with Teen Vogue, Sink says that the reason for this is because it makes the roles that she plays more believable, stating "I think the more private I am, also, the more believable the roles can be. I don't want anyone to know anything about me in my personal life or know too much about who I am just as Sadie, because I think the louder that gets, the quieter the impact of your characters can be."
Sink identifies as a feminist, which she describes as an obligation for women. She became vegetarian in 2015 after watching the documentary film Food, Inc. (2008). A year later, she went vegan; her Glass Castle co-star Woody Harrelson's family inspired her to try it. Sink uses her social media to support local shelters and encourage her fans to become vegetarians or vegans.
