There are rumours, and that’s it. All just speculation and will be for a long time I expect.
No ones even leaked any genuine iPhone 9/SE2 info really and that was supposed to be launched this month before everything went to crap in the world.
5G isn’t even ready worldwide, it’s likely to happen but it wouldn’t surprise me if only the Pro models got it.
The USB-C rumour has been ongoing for years, to be honest it’s unlikely to change on the phones. Apple just don’t feel they need it, as they’re not really meant for heavy work loads where an alternative to the Lightning connector would be beneficial. I think port-less will probably come before USB-C. But again, I’m just guessing.
