@InsertUser It's the latter: I intend to gather a group of volunteers to survey cycleways in a city, to later use for advocacy and to publish in online media. So it's a bit early for policies. I'm focusing on a practical side: e.g. many officially present cycleways can't be properly cycled irl.

For small groups and areas a uMap map might work for notes and lines? Not very mobile friendly though, it's more for display than collection.
For non-OSM data collection in the field I've only heard of QField and Mergin maps. They both rely on a #QGIS file to set up the forms and data layers and I think they can be configured for users to attach photos. I've never used either seriously though (just a hobbyist), so I'm relying on their own case studies/media relations.
