I have some pretty good experiences with PaddleOCR but you may refer to this Chinese and badly documented ones.

For our use case PaddleOCR + LLM has been quite nice combo.

Yes, that's one of the ones I tried. It seemed to be more designed for things like receipts and menus rather than books. But in any case, I found it hard to set up and use (and it's likely slow on the CPU compared to Tesseract, which despite its low accuracy, is at least very fast on CPU).
