Sorry, but all the anecdotal evidence I have is that hand selling at fairs produces the most paperback fiction sales, unless you are an author with the kind of following that wants a fancy edition and autographing. At this time of year, perhaps ads pushing the paperbacks as gifts might move some.

Paperback marketing is tricky because paperback buyers tend to be much more likely to prefer trad books to indie ones, at least in my experience. Advertising the book in other ways will probably cause a small number of paperback sales if someone comes along who is open to indie but prefers paperback. Most of my paperback sales are in my two titles that are closest to lit fic (because the lit fic crowd also seems to be more paper-oriented).

Last month, I did try including the paperbacks in one of my AMS ads (the one with the two lit ficish books). I saw a small increase, and the ACOS improved--but it still wasn't yielding a positive ROI, so I can't really recommend it.

There are a few authors who do that, as I see them on Facebook as Reels.

I'm not sure it works unless what you're doing is quirky. Even then, I'm not sure it sells books.

Isn't tiktok primarily a video platform? How do you market books on it?

It probably is worth a separate question. I'd certainly be interested in hearing about people's experiences with Tik Tok.
