It's been a while, but I've made full grocery runs using my Worksman front-loading tricyle and also with my Arpan low-gravity bicycle.
The trike is wide, and if you ride in a road, it will more or less force you to take a lane. I could get to two different grocery stores using alleys and bike trails, so that wasn't an issue.
Both of these bikes are single speed, with coaster brakes. So with heavy loads, you need a flat route, due to gearing and due to brakes. But that I also have.
Result is, that for me, a Worksman front-loading tricycle, a Worksman low-gravity bicycle, the Mexican-style cargo trikes, etc., would all work fine.
If your route is hilly or requires you to ride more vehicular-style, the bakfiets-style make a lot of sense, even at a much higher price point.
But, if it's flat and you have good access, you have lots of other options.
And too, the cheaper bikes are better from a theft standpoint.
And even if it makes no economic sense, there's no reason not to just buy a bike you especially like- that's how people pick out their regular bikes.
