can you recommend me some tructure and biome mods?

I love playing vanilla minecraft but with how the massive minecraft world is, it feels empty.
So I want some mod recommendations that add these things to the world
New biomes to explore
New structures and dungeons
New villages
Ocean structures
Underground caves an biomes
Some new enchantments

Modpacks works as well
I have a PC with
Ryzen 5 5600g
Vega 7 graphics
32gb of 3200mhz ram
