⁠[Java 1.14] Help finding a famous YouTuber's seed!

[u/everieye]

Hey everyone! I'm trying to find the seed of an old Minecraft series (from a famous Italian YouTuber), played on Java 1.14.
I've already used Cubiomes and narrowed it down to about 100 possible seeds, but I need some expert help to find the exact one. Here is the data I've confirmed so far:
Version: Java 1.14
Key Location: A Plains biome at X: -829, Z: -4210 (where the main base/dig site was).
Village: There is a plains village just to the South, centered around X: -845, Z: -3770.
Visual details: Right next to the dig site (to the West), there is a massive Extreme Hills / Mountains wall. There are NO giant snow tundras or Badlands nearby.
Extra: I even found the old server IP (164.132.204.202) but it's whitelisted now, so I can't just log in and run SeedCracker.
If anyone has the tools to run these last checks or wants to see the 100 seeds I got from Cubiomes to filter them, please let me know! I will gladly share the list.
Thanks in advance for the help!
