Best way to store loaded data ?

I just have a Data ModuleScript that handles everything internally. There's settings for each thingy so that leaderstats can be made to display certain bits of data... but everything for me is stored in a table in the script. And then to retrieve or modify information, BindableEvents/Functions would be used to communicate with it. (I never have a RemoteEvent/Function directly sourced to it). This way changes can be queued and saved effectively (i.e removing items from the saveQueue list that are in the queue again later but with a different value).

local dataSettings = {
    {
        Name = "Coins",
        LeaderstatType = "IntValue", --optional
        PlayerPointsCoefficient = 40, --optional & "pointsToAward = value * PlayerPointsCoefficient
        IsOrderedData = true --whether to use normal DataStore
    }
}

And I just run through this table creating stats n' stuff when a player joins.

local playerData = {}

newPlayer = function(plr)
    playerData[plr.UserId] = IndvidualPlayersData
end
