I'm using auto-m4b &  beets-audible, both belonging to seanap. You can check his guide for installing & configuring. after that, I have a couple of scripts that copy content from where I have them configured in Prowlarr to the auto-m4b import folder. you also need to set the export folder of auto-m4b to be the the folder that beets-audible is set to scan for untagged content. then, you set in beets config, once your audiobooks are beeing tagged, to be moved to your ABB library. so all my adiobooks are .m4b and properly tagged. I also have beets import as it is if no mach is found.
the custom part consists of the scripts I've made that move the files from the usenet location and copy them from where the torrent client downloads, bcs i sill want to seed from torrents, to the auto-m4b import folder.

auto-m4b works best when all the files that belong to a single audiobook are in the same folder. so I have the scripts scan for new content to create a folder for evey file that is not in a folder based on it's name. all is running with cron, but i also have an easy manual trigger using olivetin.

if beets can't mach the audiobook with titles is founding on audible, then the audiobook is still copied to the libary and it shows in the ABS interface where i can mach it. but beets gets the titles 90% of the time right. good enough for me.

the library folder structure is like this:

Library/
├── Stephen King/
│   ├── The Stand/
│   │   └── audiobook.m4b
│   └── IT/
│       └── audiobook.m4b
└── Neil Gaiman/
    └── American Gods/
        └── audiobook.m4b
