I have an ambivalent relationship with such tools. On one hand, ensuring compatibility between participants in a game is a high-priority goal. On the other, some of the stories of implementing the pursuit of this goal make me super-concerned and put off by the way some advocates want these tools to be used.
The concerning parts are that some of the proponents come off as one-true-wayist, almost 'cultish', about some or all tools. Roleplaying spaces which mandate use of some list of tools, or people who see tools as thought-terminating conversation-enders rather than conversation-starters or conversation-aides. I suppose those 'horror stories' (I thankfully never got to experience something so drastic first-hand) influenced my reluctance to use formal tools even though I've grown inclined to grab their ideas and use them informally.
As for the more specific tools/approaches, I suppose the ones I consider the most relevant can be mostly split into two categories: those that are predominately pre-emptive, and those that are predominately interventive, and I'll comment on them separately.
Predominately pre-emptive / pre-game tools, mostly represented by line-veil-like stuff. Seems like a great way of ensuring player-vs-topic compatibility and, depending on whether a topic is essential to the plot/settting/whatever, filtering out campaigns/players that are not mutually compatible, or adjusting the palette used in a campaign. At this point I settled on describing the broad strokes of what sort of controversial content is and isn't likely to be seen in the campaign and how it's handled, maybe include a media touchstone/example or a few (e.g. 'there might be body horror, but no worse than can be found in Miyazaki/Ghibli works'), and asking players to informally add to the discussion (e.g. suggest extra constraints, ask for clarification, &c.).
I do see the utility of checklists sometimes, but am not the type inclined to rely on them. I'm also bothered by the phrasing in some of those checklists, particularly when a list jumps from 'OK when veiled' to 'enthusiastic consent' without an intermediate greenlit option of
neutral consent. I'm sorry, I am not comfortable putting 'enthusiastic' next to maybe half the entries in those lists - putting enthusiastic next to them feels like asserting a kink and/or asking to please add more of that content into the game, and that is very much not what I'm trying to convey. Like this one:

checklistI'm also a bit ambivalent about such lists because perhaps the best horror scene memory I have comes from a campaign that came with no checklist and no forewarning, and I think the scene wouldn't've had such a cool impact on me had it come with either a checklist or other similar discussion of content categories including the one to which it belonged before the campaign.
The other category is the interventive tools. The Card-like ones. Again, I'm not the type inclined towards formal variants thereof. I do recall a use-case when an informal analogue worked out pretty well, with a player asking to steer away from certain content and that was exactly what was done (I was not the GM, but I was part of the cause of the content). It was a clear adjustment request conveyed in clear language with enough information to figure out the approximate boundaries that needed to be added around the topic from that point onwards.
By contrast, I'm wary of the way
at least some advocates seemed to present the card and the rewind, as a no-discussion-no-communication kind of red button that interrupts scenes and retcons the plot/setting at the slightest discomfort. I get that the big red button emergence brakes are worth
having, I don't think they should be used so lightly. I think topics that are worthy of the big red button are definitely worthy of preventative measures - the only exception I see if the big bad topic was so outside the campaign expectations that it was never thought to be encountered in it (example: warcrimes somehow coming up in a Golden Sky Stories game).
