That's wrong question. It usually doesn't matter what is banned, but what is "shadow-banned" really matters.
You can't see what is shadow-banned on Facebook because they don't tell us how they do moderation on their news feed.
I haven't seen a reason to suspect that TikTok have been any more open about their moderation policies than Facebook or indeed any other social media platform have been.
It's possible to reveal __some__ policies (like trivial one with breastfeeding), but I think that reverse-engineering of non-trivial policies is really hard.
Like moving some type of content to the bottom of the feed for some category of users. It may not look like a ban, but who is gonna scroll to the bottom of the feed? Or 25% bias in news priorities of one political party over another for some users.
Their non-trivial policies may also change over time, so it would be hard to prove any of them. They had years to optimize their news feed.
And who will have time and knowledge to do statistics? With millions of eyeballs we still have tons of trivial bugs in open source software.

I don't know any of big news players who have open editorial policy, but TikTok is new in the industry and I think they don't have knowledge and technologies to develop non-trivial policies like Facebook, Twitter, NYT or any other big player.
