Indoor/Hydroponic Gardening?

I was recently gifted two indoor hydroponic gardening systems and I'm curious what y'all would use them for from a prepping perspective.

I'm in the northeast US, so I can't grow anything outdoors in the winter. A lot of people use these for herbs and strawberries because they have good yields while taking up a small space. However, I grow a huge garden in the summer and preserve my harvests. So they're dried/frozen/canned, but still, I have plenty of both.

Is there anything you'd suggest? I'm wondering if there might be something that has a good yield in a smaller space, but is higher in calories than strawberries or herbs? Or, maybe something that would be difficult or expensive to get under any sort of supply chain disruption? I'm considering a tea garden or salad greens right now.

On a similar note, is there anything you grow indoors throughout the winter? I did micro greens last year and loved it. I'm curious about any cold-weather indoor garden suggestions in general from this group! Thanks!
