Three very good choices. Despite all three being law adjacent in many ways, as a lawyer I'm going to highlight Brenda Hale, otherwise known as Baroness Hale of Richmond. One of those rare judges that is sufficiently famous that many non lawyers will at least know her name. Her headline achievement is being the first woman to sit as the President of the Supreme Court, but she was also the second ever woman to be a judge of the Court of Appeal, and the first woman to be appointed as a Law Lord (a judge who sits in the House of Lords). But outside of those headline roles, she is considered to be one of the best and most prominent judges of her generation, which is made all the more remarkable by the fact that she was an academic lawyer, and therefore had a really unconventional path to the judiciary in the first place. You can obviously read about her on her Wikipedia page, but I'd also recommend her biography, Spider-Woman, which was named due to her becoming well known for wearing a spider broach when she delivered the Supreme Court's judgment in Miller 2 regarding Boris Johnson's decision to prorogue Parliament (also the reason why many non lawyers will know her name).
