Install a Standard Minecraft 1.18.2 server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Standard Minecraft 1.18.2)
For a normal Minecraft world, it works really well, its simple, and the monitoring tools are really helpful for finding problems. Although, if you want a server with a lot of mods like I tried to do, the amount of RAM you need to sustain it can get a bit pricy.
