I found this article very helpful - and basically the answer is be careful and only do so if you work with IT.

Get real value for your money!
One real value for a dark web scan is awareness. You should be able to obtain an initial dark web scan free of charge – without paying an ongoing monthly monitoring fee, which we certainly don’t recommend. The initial report will help identify if you have law firm employees that tend to reuse the same password across multiple sites. It may even identify sites you were not aware of so that you can immediately change the password. Use the dark web scan to educate employees at your next cybersecurity awareness training session. If you’re not teaching your employees about cybersecurity, at least annually, you are missing a very significant part of cyber resilience! A human element is involved in data breaches 82% of the time.
Take control of your data and don’t hand it over to a monitoring service. You should be using a password manager and a unique password for each website or application you use. Put a freeze on your credit file at the three major credit bureaus. Freezing your credit file is free. Why would you want to pay someone to monitor your credit score since freezing your credit file will stop a huge amount of identity theft opportunities? A lot of credit cards offer free credit score reports too.
