Enhancing B2B Outreach: Ideas for Effective Contact Enrichment

I am a B2B outreach specialist working on helping my clients target better contacts. I already do simple email waterfalls. I have a lot of credits to use. What are some other enrichments that are good to use that can help with b2b outreach? I see there are find news info about the company. Any good ideas of what to add to the automation? I will have business name, domain, business and personal LinkedIn, email, basic company description. I do not want to run lookalikes. I have an API and credits for that.
