I’ve used Optery since they posted on Hacker News a few years ago. Really satisfied with them - I get quarterly reports that show screenshots of my information being found on a site, then the same site and search not showing results after they’ve finished the takedown. The spot checks I’ve done myself show the same. Can’t find me by phone number, name, etc.
They have different tiered plans and over time I’ve upgraded my account to the top one for a few hundred per year just for extra peace of mind and to support them. Their plans range from $3.99/mo to $24.99/mo.
I’m sure there are better by now, but I’ve been satisfied overall
