Also what do you think of KartaView? I'm not sure whether to trust the Meta owned Mapillary, even though the current data has an open license.
My problem with KartaView is that there is no new images in my city since ~2019, and very little is covered. So no one here uses it. While someone needs to start, I guess, it wont be me. The municipality where I live has however mapped >800 km of city streets themselves in Mapillary, so it's a good source to expand on and where I can fill in the gaps with cycling related stuff.

As I'm just a beginner I don't think a 360 camera is worth it just yet, they are quite expensive compared to regular ones. And I can imagine putting it on my helmet would get some attention from bypassers, unlike a normal camera mounted on the handlebar.
KartaView itself was never free of Meta. One reason it was never accepted on F-Droid is that it required Facebook libraries to build.
