Thanks for the nice comparison!
One question though: is there a way to search for unlisted topics, or see them all in one place? I am a moderator and I want to see topics that have been unlisted by other moderators, is that possible at all?
AI-generated summary
A moderator, Vikteur, asked if there’s a way to search for or view all unlisted topics, including those created by other moderators. JammyDodger suggested adding ?status=unlisted to the site’s Latest page to view unlisted topics. However, this method only worked within specific categories. To view unlisted topics across all categories, JammyDodger recommended using the URL [YourSite]/latest?status=unlisted. This solution worked for Vikteur, who noted that the alternative URL [YourSite]/?status=unlisted did not work due to their site’s homepage style being set to ‘Categories’, as confirmed by JammyDodger.
You can add ?status=unlisted to your Latest address to provide a handy topic list. 
@JammyDodger thanks for the fast reply! This works for me, but only when choosing a certain category. Is there a way to see unlisted topics across all categories?
You should be able to see all of them if you add it to either [YourSite]/?status=unlisted or [YourSite]/latest?status=unlisted. When I check here on Meta, both ways list them for me.
[YourSite]/latest?status=unlisted worked for me, the other one didn’t. But it’s fine, I can work with that. Thanks a bunch!
Ah, I wonder if that’s because of your homepage style. We have ours as ‘Latest’ here on Meta, but it may not work if you have yours as eg. ‘Categories’.
I’m glad the other link format worked though. 
We do have ours set to ‘Categories’, so you’re right
