If you’re going to run Minecraft then Google “Paper MC”.
Honestly would much rather recommend Fabric unless you’re looking to host a large scale public server. Serverside optimization mods like Lithium and Starlight are great and preserve the vanilla gameplay unlike Paper which breaks or disables a lot of mechanics by default.
Usually if you complain you can get a real refund. The other post was Amazon and they usually bend over backwards to make customers happy. Still pretty shitty that you have to jump through some hoops, though.
