I identify with the problem. Unfortunately, what's been working for me is not reading so I don't really have a solution. What's I found interesting is that reading became an escape style activity which was far more harmful than the actual content (Posture of Pornography hmmm?). This is a longer shmooz though.
The limited reading I do recently is just business/psychology/finance books in the bathroom, those are generally pretty clean. Occasionally I even learn something useful although it's hard to find the ones that are worth reading among all the chaff. Other options - a lot of classics are relatively clean. Think Dickens, Shakespeare, Benjamin Franklin's autobiography. If you dig hard you may even find a couple that are enjoyable. Poetry. History.
Oh wait, one crime recommendation. One of my all-time favorite writers is pretty clean (to the best of my recollection): Mick Herron, Slough House. 10/10 recommend the writing, I'm not responsible if it triggers you though

A lot of classic cozy/detective mysteries are clean - Agatha Christie, Rex Stout, Dorothy Sayers etc.
