Should be easy to use, remember what I bought before and propose things that are probably running out (based on my personal buying frequency), and allow sharing the list between multiple people. Ideally also allow adding recipes for meals that I cook often.
At that point, you might as well get Mealie.

Yeah. If you are more into the recipe side of things Mealie is imho the way to go.
If you want a ERP at home Grocy is more feature complete,but also more bothersome.
