Need a table NOT logged-in users can modify and/or edit

In a members area registered users can checkmark and / or enter data into cells of predifined rows and columns. Process should be as follows:

1. User can register on the WP-Site
2. He gets login data e.g. by email (username, psswd) to enter members area
3. In the members he sees a table. Certain cells he can checkmark in others he can enter text. He is only allowed to edit this page (table). Nothing else on the entire site!
4. After he is done he can save his data and leave the page

Other members can view his data and enter their own info or check cells (peferably he can only enter / modify his own data)
No member can enter the dashboard or enter the admin of the wordpress site

Question: Which plugins I need to install and handle this process? I need a solution which is super easy to work with for the (dump) end-user. Maybe front-end editing would be an option?

I checked wpdatatables-plugin (https://wpdatatables.com/) but I think it is too much for my need. I also have seen these plugins. Not sure if they will fulfill the task: Pie Register (Plugin), Sidebar Login (Plugin), User Access Manager (Plugin)

Any suggestions? Thanks a lot for help. Cheers Oliver
