A standard vented coffee bag has… a vent. So some smell is expected.
I just keep old coffee bags around if I need to store grounds or separate smaller quantities of beans.
I believe the objective is to reduce beans’ and grounds’ exposure to air, to reduce oxidation and flavor oil evaporation, so a standard coffee bag is the best way. Just squeeze out most of the air as you’re resealing it.
Storing in airtight jars leaves too much air, IMO.
