Pickup + or Unlock Plus with Pickup
I would also encourage you to remove Litman’s mods since Litman is no longer modding. Use Testerle’s Stacksize Plus instead, which allows you to configure the stacksizes yourself using multipliers.
For Container Size, I recommend Unlock Plus with Pickup for the same reason. You can configure the container size. If you choose to use Unlock Plus with Pickup, you should also remove Pickup +.
