I think by law they have to make it as easy to opt out as to opt in. So for almost all the websites I see, clicking 'More options' defaults to everything off. I now do 'More options' > 'Save' on autopilot (and if one or two bad 'uns slip through the net, so be it - life's too short).
The only problem is that there is often an option to allow cookies to "store site preferences" or something along those lines.
My experience is this also includes your cookie preferences which means if you don't enable that single option, you'll have to go through the steps to disable cookies pretty much every time you visit.
And NOYB has started pushing for more enforcement, so it's likely sites will become more compliant.
It turns out that those third party "consent form in a box" solutions tend to have settings to let the website operators choose how user-hostile the popup is supposed to be. It's a shame the DPAs are all understaffed, incompetent, unwilling, or willfully looking away (e.g. in the case of Ireland) instead of taking expensive enforcement action against companies that violate it.
A few expensive examples and every site would have a top-level, equally visible "reject all" button, and after a while, sites would realize that with 90% of people choosing that, they might as well skip that popup and assume rejection.
Those popups aren't mandatory at all, sites can simply respect your privacy by default.
