I've settled on Apple Reminders (yes the stock one that ships with every Apple device). For a month, I made lists for each shop I bought stuff from (costco, safeway, sprouts, etc) adding whatever I bought there. With those in place, the pain of grocery shopping is reduced to going through the list and picking the usual suspects. One habit that made it even easier was to make sure the list is updated the moment I think I need to buy something. (iCloud sync across devices is a lifesaver here. Siri is also useful sometimes) This extends to meal prep too. But that's not a problem I have today. I look for no further solutions on this.
