Storing seeds with a humidity control pack keeps them in a stable range rather than swinging with the weather. The trick is picking the right percentage, since the packs made for cured flower are too moist for long term seed storage. A short note on https://potentthcseeds.com compares the different pack ratings and explains why the lower ones are the right choice for seeds. Combined with a cool dark spot, this is about as low effort as preservation gets.
