Wordpress, how to implement registration with filling out a questionnaire and displaying this information in the frontend?

Question

User identification

Hello, this is my first question on the Toaster..
The essence of the question:
The user enters the page with a profile, a lot of questions, from checkboxes, radio buttons.. Fills out. With this data, a letter is sent to the admin, saved in the database (Contact Form 7))). It is displayed on the page accessible for example to the "manager", A list of such questionnaires is displayed, with data entered by users. Sorting questionnaires.
The manager also has a page with a questionnaire that he (she) fills out from the client's call.
The manager sends the selected user a brief filled out from the client's call.
Export to excel.
And this is only at the beginning%)
Is it possible to implement THIS on WP, using plugins, the customer is a fan of WP...
How best to implement it, in the sense without WP, it’s most interesting to write it with pens, to gain experience and knowledge, to raise it on a subdomain and without WP, but I’ll write it for a long time, I’m just learning, but I need to do it quickly.
What do you suggest, any solutions are interesting.
Thank you.
