Airtable is great for prototyping an app.
Airtable does have a Forms feature built-in, it is very basic on the formatting side but does have nice features like required fields and conditional fields. Airtable recently launched Form in their Interfaces modules, which gives you more layout flexibility and user control, but loses some of the other functionality (as it stands now, I expect this to receive more updates in the near term).
If you want more control there are plenty of 3rd party form app that work with Airtable.
Airtable can also send out emails or slack message, and you can hook it up to an automater like Make.com to give you more flexibility.
If you want to stay fully No Code, you may want to look into a more robust stack than just Airtable alone. Maybe something like Softr.io for the front end and Airtable and Make.com on the backend.
