I like the idea of using one of those bike trailers for kids, as you could use it as storage on the go. Though I think I’d want something with more protection. But if you’re going to and from one place, then it should be fine.
You can use rear seat carrier trunk bags, it’s very useful and stylish. It’s made up of waterproof material, you can keep your groceries or supplies when you come back home from shopping.
You can attach baskets at front and it would look cool on retro bikes. You can also be sure, your items are safe when you ride. Since your items are in your eye sight.
