Storing player-specific data

[rose flame]

Hello! I'm fairly new to working with the Spigot API, so I apologize if this is a dumb question.

What is the recommended way to store per-player data? I'm used to Forge, so my first thought is to add tags to the player's NBT. However, I'm having a hard time figuring out how to do that with Spigot/Bukkit.

I just need to store one block position and a couple of flags

Either make a data file named with their uuid, SQLite, SQL, or PDC

PDC being the equivalent of NBT
