I've actually drawn this already in a fictional setting, but things like an outdoor art space, a town pollinator garden, a nice place generally to hang out in, and parkettes among other things. Basically, what I think would be nice to have in a town is already depicted in the artwork I included in this reply, minus the anthro bunnies obviously because anthro animals are of course a fictional construct, but the stuff I'm depicting is the stuff that would also be nice in a real town.
Ooh, sliming booths scattered around town for friend or family photo traps would be fun too, as long as ponchos are supplied to protect people's clothes of course.
Of course things like never-ending art installations that the public is perpetually free to add to at will, like, say, a fence mural that can be constantly added to like I depicted in my outdoor art space drawing, would be nice as well.
