Not sure if this has changed in DOS2 but in EE I always ran into the issue of not being able to sell gear easily when using bags to organise and segment my inventory.

I kept all crafting objects in one bag and the problem I ran into was say I wanted to craft a superior axe, I would turn a steel bar into an axe and this axe would then be placed in the bag once created. When I go to sell said axe, it is stuck inside the bag and I only have the option to sell the entire bags contents in one go to a vendor. To get around this I either have to hold the axe and drop it individually into the main inventory (time consuming when creating/moving multiples) or drop it on the floor and pick up again (slightly quicker).

Bear in mind I am using an xbox one controller for my playthrough which may affect inventory management.

Suggestion: Either allow visibility of bag contents when selling so you can select items individually within the bag or put created crafting outputs into the main inventory to allow for sale.
