Any real business needs to do behavioral tracking for campaign conversions, add-to-cart, customer acquisition, funneling, retention, personalization, etc.
I love how we all hate cookie banners and say they are unnecessary, but are salaries are all paid by apps that do behavioral tracking.
Only hobby blogs can get by without it.

There's no _need_ to use cookies for tracking purposes though, it's usually just easier/cheaper/quicker (or requested by the marketing department) to use off the shelf software than actually spend the time to implement these things.
But if you have a cart, you need a cookie banner regardless of any tracking you are doing.
you don't need a banner for shopping carts, or personalisation
the heuristic for whether you need the banner is essentially: is the user deriving the benefit, or just the operator?
if it's the latter you definitely need the banner
It's a shame this is downvoted. It doesn't make it right, but it is true.
Until the regulation actually gets enforced so that everyone is on a level playing field and does not do such things, you will be at a disadvantage if you're the only one to comply, so the winning strategy is to not comply and engage in such practices just like your competitors do.
You can track conversions exactly without using analytics or cookies, by using promotion codes.
I appreciate the list of reasons to cookies are useful. Despite having worked in technology for 25 years, I couldn't have articulated that list off the top of my head. I have never worked for a website that made money that way.
I think that means not ALL websites need invasive tracking.
