Seeking TTRPG Content Management Software

I have a collection of TTRPG books/PDFs (rulebooks, short adventures, long adventures, etc) and I'd like a way to organize them in a way that's usable. Grimoire seemed promising, but it seems to be new software that's still a little buggy. I also have like, nearly 50k tokens (small webp/png images) and battlemaps (larger images) that i would also like to organize. Immich is an option, but it doesnt seem like the correct tool for this. Maybe pinry? But idk if it could handle libraries this large, Can anyone recommend any software?
