I have a lot of SD cards with the original DNG files. When I want to find the appropriate card to review the DNG image in Lightroom Classic, I need a way to read from the EXIF data which card to pick. At present I have to read a card at a time to find which one to use. I will try to organise my cards better but the ideal way would be if the SD card's identifiers were recorded in the EXIF data of each image file. This would mean that if I loaded the jpeg file into LR classic I could then read the SD cards ID which I could then relate via a spreadsheet file hat mapped Card IDs to my system of card organisation. I'm sure that other photographers will have a similar need. Adobe please help.

As the above post by @Axel Matt this is not the place, forum, space, for asking for Feature Requests. Follow the link in that post.
But I must say I don't understand your question and the need for that option to be added.
When importing your images from the memory cards of your cameras the images should be Copied to one of your hard drives into folders with either Dates as the folder names or with some type of description as the name as to where they were taken and or something that make you remember where and why you took those images.
All of them shouild be available in the LrC Catalog file and on some hard drive that is connected to your system in some way.
If you want to use multiple memory cards (SD type or whatever else) as some type of Backup system of those images that is fine. But all of them should be on a hard drive and then Backed Up to other hard drives.
Hard drives, Hard Drive Space, is much cheaper to buy than SD, CF, Whatever type, of memory cards.
If you are using these, Whatever style, memory cards as your backup plan I wish Good Luck with that.
Have you ever heard of External Drives? Real Hard Drives, rotating, or Solid State (SSDs) type?
Those can hold Multiple Terabytes of data in one package
They usually connect by a USB port on your computer and can be used for Storing your image files and LrC can access them Directly. Then a second and third external drive can be used to Back Up all those original DNG files that are on the First External drive. Then you can recycle the SD cards.
Having multiple copies of all your important files is the only way to make sure none of it is lost.
Redundancy is the only way to make sure you don't lose your data.
Best of luck to you whatever you decide to do.
SD cards are not a viable backup media, those cards will fail one day.
LrC does not show all Metadata. You would need a third party exif reader like Exif Viewer, or, perhaps for your workflow a plug-in fir LrC such as Jeffrey’s “Metadata Viewer"
