CRM Lead Magnet, Forms or MarketingHub for forms on a website?

I want to add forms to my WordPress website. I want the forms to pass data to Zoho CRM and I will want Zoho MarketingHub to automate processes on the website. So, which Zoho forms plug-in should I add to my website:
1. Zoho Forms?
2. Zoho CRM lead magnet?
3. Zoho MarketingHub?

Many thanks

Steve
