Does Office 365 (or whatever it is called these days) have a version of Google Sites?
The only thing I can think of is SharePoint, but that’s more targeted at business and Intranets AFAIK
I think there are third party businesses that attempted to be “online office suites”. I don’t use Google’s service, so I have no idea how anything compares to it, but from a branding perspective, ZOHO was the first one that jumped to mind, but I am sure there are others. Looking at ZOHO they have a forms service Form Builder | Create Free Online Forms - Zoho Forms and an office suite Powerful Online Office Suite For Modern Teams | Zoho Office Suite
