Here’s a list of plugins I personally use, Unfortunately it’s not everything you’re after, but somewhere to start, I guess.
LuckPerms (Permissions)
Nucleus (Essentials)
Grief Prevention (Claiming)
TotalEconomy (Economy)
AdamantineShield (Block Logging)
DTPunishment (Chat filter and auto mute/ ban system)
DTCommands (Link commands)
Activetime (Playtime tracker)
CarrotShop (SignShops)
DailyRewards
MMCReboot (Auto restarts)
PixelAutoMessages (Automessages)
As far as I’m aware, there aren’t any plugins similar to Hotels or TreeAssist, but there is Project Worlds and GWM Auto Mine Reset, although I haven’t used either of them personally. I’m not sure about a clans plugin, and I don’t think we have any working minigames plugins at the moment (You’re probably better off making a separate server and using bukkit for that, they have way more than we do currently).
You’ll find most plugins here: https://ore.spongepowered.org/ but also you’ll find others on Plugin Releases on the Forum.
Hope this helps!
