Hello, mr_absinthe,
Thanks for your message. Showing the banner is okay as per my study. The banner will be shown after 365 days when visitors accept cookies and will not show again when visitors visit the website from the same browser again. The cookie policy link has all details about cookies, their usage, and related information about cookies.
There are different types of cookies like analytic cookies, authentication cookies, cookies used by social networks, and cookies used by external content add-ons. One accepts button for all instead checkbox or option to choose selected cookies by the banner.
I see in your image a checkbox is given for each type of cookie to accept which is fine.In your screenshot options are given for each cookie to accept using a checkbox and in my module one Accept or Ok button for all cookies
I will share the online article and documentation link later to confirm my understanding.
