Hi
To the best of my knowledge production date and SLED date is a characteristic of Batch which has no relation with Storage unit or Handling unit. While you can decide whether multiple batch can be stored in one SU or whether Stock can be mixed based on your product and warehouse process/ Layout and product profile.
In my personal view SUM and & HUM and no direct relation with Production date / SLED date hence if your warehouse is not SUM or HUM managed no need to worry from Production date / SLED point of view.
As you mentioned that you can go with Quant then again you have to look that the moment we add any stock the Quant data gets overwritten so you have to decide your putaway strategy very carefully which can help you to achieve FIFO at the time of picking using Quant
