The problem with minecraft modpacks

My issue with most modpacks (Better MC1-5, Prominence, etc...) mods is that they are so overpacked and feel sooo overwhelming, especially since they dont have a dedicated wiki page or guide. You could complete your playthrough with these mods while missing out on some core mechanics or items accessible.

I am looking for something thats simple and can be figured out simply through playing. Like include a couple of extra biomes, maybe a new boss or 2, even new ores/resources. I dont want to get bombarded by 20 different ore that are essentially useless and used for 1-3 items.

I would really appreciate any recommendations and hopefully this benefits other people too!
