You have highlighted the point I was making.More advice on number 5. please
Last night I spent half an hour deleting cookies on a site that gave a recipe for green tomato chutney , and hadn't got even 1/8th of then way down the page ruler showing how many to go .
It should be an easy task and on some sites it is but on so-so many the task is made deliberately onerous.
I have found, " reject all " doesn't reject all, permanently checked/on selections -- hides a whole lot of cookies/spam.
Some sites I have found reverse selection buttons or colours.
"Save and Exit " for that visit maybe, revisit the site, back to square one.
" Customise " as I suspect you have found opens up a whole world of disabling/turning off, worse still, miss one selection and sites assume, regardless of your efforts, you are giving permission to enable all, you don't actually mean your selections.
Nope!, if sites wants to get its spam and cookies on you PC they will find a way.
Clearing you browser/cache on a regular basis does help but it's an unwinnable battle/onslaught
" Reject all " should mean just that but it doesn't.
