Is there a way to check sites by content and keys at the same time for a list match?

Colleagues, hello!
1. Suppose I have several hundred sites.
2. I have a list of words that are relevant to my queries. For example, everything about cigarettes: smoking, cigarette brands, smoking treatment, etc. - dozens or even hundreds of words.
3. I have a need to check all these sites for matches on all keys. I can do it manually via ahrefs, but it's a long time.
4. I also have a need to check all these sites for the presence of words in articles or content for example, "cigarettes", "smoking treatment", "cigarette brands", etc." I can do it manually via google and the site operator: site:domain.com 'word', but it's a hell of a long time.
Is there any service or method that can check all these hundreds resources for a match on any of the 1.list of keys in serp and 2.list of words in content fast?
Thanks.

Scrapebox can definitely do this, but I'm not sure of the exact functions (but probably with the Page Scanner addon and the list manipulation functions of the main software).

But given how long it might take to learn how to do this with SB you're probably better off doing it manually
