If there is space, I would have one of those narrow pull out shelves on wheels that can go behind the fridge or into small spaces between cupboards or somewhere. They are great for canned good or spices.
You could look into one of those shallow cutlery drawers that go on the top of kitchen drawers.
Some of the other things I use are:
Shelf extenders in cupboards, use cupboard doors for hanging things or saucepan lids.
Wire shelving on the back of the pantry door, for kitchen foil, bags, etc.
If the kitchen cupboards don't go up to the ceiling, fill that space with more cupboards on top, for things that don’t get used often, like Christmas items. (This might require help to get at them)
Loads of hooks. For example, all of my pans are hung up on one wall of my pantry, except for the posh ones that have their own stand.
I also hang drainers, colanders, etc from the pantry ceiling along with wicker baskets.
Magnetic shelves bars and hooks on the side of the fridge freezer, for towels, drying up cloths, oven gloves, etc.
Plate racks are good uses of space, for chopping boards, plates, trays and baking trays.
Magazine racks are good for small packets.
I have a cord between the walls of my under sink cupboard for drying cloths and a tension rod from which I hang squirty bottles of cleaning stuff.
