For town/utility I *usually* find a basket more useful than a porteur. Although incorporating the best of both worlds could be optimal. Probably easier to buy both and then fit as required, what is it, three bolts?
For around town I prefer Raleigh North Rounder trekking type bars with cork ergo grips.
If you’re going more sitty-uppy it’s also worth thinking about the seating arrangements.
If you’re looking at going ‘hipster’ then maybe look at pictures of pathracers or turn some trekking bars upside down? Possibly fit bmx bars to an old Bridgestone or Peugeot etc. Fit a porteur rack then jubilee clip an old supermarket basket on to it. With a Tiswas badge on the front. And some Frosties on there, secured with a honey-brown leather strap. Spokey dokies. Or something, I dunno something pseudo-post-ironic with a twist, I dunno! Howabout recreating Evil Knievel’s jump bike except as an urban hipster fixie???
I get carried away. Sorry. But I like that last idea best.
Here’s a bike with some wrong brake levers:
