Used to do groceries with a regular bike and two ortlieb panniers (you can leave the top open to use their full capacity)

For extra space a front "Porteur style" rack is nice (you can carry a pizza or takeout), or a rear rack with a set of lower mounting rails allows carrying stuff ontop of your rack without interfering as much with the panniers.

some people also really like the topeak rail system, which has for example a little wheely cart you can pull around the store with you, the "Topeak TrolleyTote"

Over the summer I bought a used (not electric) bakfiets on craigslist (and only recently did a mid-drive electric conversion) it's been really great for doing more with a bike because it doesn't take as much "how am I going to carry this home" planning. I've picked up groceries, dog food, filing cabinets, my wife, my dog, friends, lumber, tools, etc. It's quite an amazing bike format.
