Usagi Drop ends with the daughter and parent marrying, so theres some child grooming there and I wouldn't recommend watching it without letting people know to ignore the ending at least.
The anime doesn't have any of that. Also I've actually read the second part of the manga and while it wasn't especially good, it wasn't nearly as bad as people make it out to be.

not in the anime
That does not happen in the anime which only adapted the first part of the manga. Also spoilers.
"There's weird weeaboo incest shit" is the kind of thing that should be spoiled in big block text on the front of the packaging.
