I found Readarr similarly underwhelming, but OpenBooks is really good and easy to use. It downloads straight away to the client and the optionally also the host, so the books are stored in the library permanently. I have Calibre monitor the host's download folder and use Calibre-web for the frontend, but I would assume Moon Reader would work decently with Calibre too.

libgen, but a few of those sites have gone down
I use readarr, calibre, calibre-web, prowlarr, and qbittorrent-vpn . Works great. I add a couple goodread lists to the readarr import, and it gets everything my friends/family want. This guide helped me immensely when I was first setting it up.
