from my limited experience with it, i think this is sort of the "wrong question". Luanti is basically to Minecraft as Garry's Mod is to Half-Life 2 (except not really, since it's not the same engine). It's basically a platform at this point, with the base mechanics of Minecraft available as components for you to build your own game with. there are many different games available, and many of those games have their own mods.
there's some automation-focused stuff in their browser but since mindshare is much smaller they are not as finished or polished. however, since there is an official modding API this time, you never know...
i didn't want to use roblox as an example as luanti is more focused on a single typ of game, and is playable in and of itself. gmod's sandbox is akin to the default sandbox in luanti, basically a creative mode.
also i didn't want to imply that luanti has child exploitation...
Luanti isn’t playable in and of itself; you need Minetest Game, which is a different thing. Just like Roblox, the similarities between games are usually as little as character + movement + 3d-ing
There are mods, lots of mods, But not any that you've heard of before and honestly largely not of the same quality of the stuff you're looking for that was available for Minecraft.
