I have virtually no space for storage in my small apartment. I hang herbs from the curtain rods to dry (they look pretty, too). I preserve jams. I don't like to depend on electricity, so my tiny freezer has some frozen fruit and ice cream. You intrigued me with the vacuum jar sealer, but the ones that I saw are made with plastic. I have noticed an increase in the use of silicone bags for storage in the freezer, as space savers. https://www.consumerreports.org/reusable-silicone-bags/best-silicone-food-storage-bags-a9831141508/
