something like this:

Answer 2

You can't say it in two words.
Personally, for me - 100% should be contact details, a feedback form, a description of the field of activity - i.e. who you are and what you do.
And then there are sections depending on the area - maybe a gallery, a portfolio - if you are a person of creativity (an artist there, I don’t know, a designer), there may be a text section with articles, or a portfolio in the form of completed sites, etc.
I think you get my point :)

Answer 3

On the business card website, you can post: name, contacts, location or "how to find us", a list of services with or without prices, a brief history of the company, description of activities, a gallery of works, customer / client reviews, feedback. Maybe even an online chat for consultations. Yes, whatever you want, in general. It depends on the field of activity and on what you want as a result from the site.
The minimum set, in my opinion:
Name
Field / line of activity
Location
Contacts
