I am considering starting a new world and I am currently trying different seeds. heres some I recently found by using three of the mod usernames.

Seed: alyaza You spawn at the boarder of a flower forest and a beach.

Seed: Gaywallet You spawn in a jungle with a river nearby with a village on the other side of the river. Seed: Lionir You start in a Savanna right next to a beach.

These are some pretty interesting seeds.

Also I did my own as a seed.

seed: Gamers_mate You spawn in a jungle next to a small beach with a dark small dark forest on the shoreline of the beach.

Edit: I forgot to mention I tested these seeds in 1.21.3 (Java) Depending on the minecraft version you use you may get a different result for the same seed. Also it is case sensitive so using any capital letters will give you a different seed.
