Looking for an aesthetic Minecraft Modpack?

I'd like to try a Minecraft Modpack because Vanilla gets a bit boring after 8 years. I've already tried all the standard modpacks, like FTB, Sevtech Ages, Rlcraft etc. But somehow I didn't like the feeling at all. I'm more looking for a modpack that focuses more on aesthetics and atmosphere. So new biomes, maybe a few new mobs, new blocks to build with, nicer / interesting nether and end, etc. It should still feel like vanilla, but pretty nice. Does anyone know a good modpack?

I discovered the Roguelike Dungeons Modpack in the technology launcher. Is recommended.
