I think Strava Local is curated, but I agree with the 'frankly, bad' part of your comment. For my home city of London it has a few of the major landmark routes, but doesn't have anything near my house, nor does it have any of the less obvious but more fun local routes.
My frustration with Strava is that they have SO much good data, yet they do so little with it.

Whereas my frustration is that they have mountains of bad data (and we're sometimes talking egregiously bad here - segment times for runs that are >10,000mph etc.) which they do nothing about. It's a trivial data hygiene problem to note that, e.g., if an activity is marked as "running" and the average speed is 20mph+ over an hour, that's bullshit.
