I found a OneBlock server called LegionCraft and it is all about building up from your own island and grinding to get stronger.
There are challenging bosses and when you beat them they can drop keys. You can use those keys for rare loot and there are crates with epic gear and rewards.
You can also use chunk hoppers to automate parts of your island. The server says it is not pay to win so it feels more fair if you just want to play and grind.

GG.MINEWIND.NET New Server IPOP Gens Lifesteal PvP Domination
Lifestealbox MC is a lifesteal PvP server where fights actually matter. When you kill someone you take their hearts and when you die you lose power so every fight feels risky.
It also has an OP generator system that makes resources come in automatically. That means less boring grinding and more time spent fighting upgrading your gear and progressing faster.
The vibe is fast paced and competitive with constant PvP and real rewards. It feels good for sweaty players and for grinders too.
The community is active and growing and people are friendly but still competitive. Staff actually helps and the server gets events updates and improvements. It also says there is no pay to win nonsense and power is earned not given.GG.MINEWIND.NET New Server IP
