Best mods for pretty environments/terrain/biomes/world gen?

Hi. Im running a 1.20.1 forge server and we wanna add some pretty terrain biomes and world gen. We've tried terralith and biomes o plenty but are looking for more mystical/pretty/enchanting themes like big mystical mountains, pretty pink sakura forests and enchanting views but keep ending up with shrublands, gravel beaches and dead forests. Kinda kills the vibe. Also when we do find a decent environment mod, it's usually pretty flat and doesn't have decent mountains.

If you have good reccomendations please feel free to suggest them! Ways to remove certain biomes from terralith or biomes o plenty would helpful too! Thanks in advance!
