I’d treat the two problems separately.

For the Wi-Fi update error, go to Settings > General > iPhone Storage. If the iOS update is listed there, delete that update and download it again. Apple recommends trying another Wi-Fi network as well.

For the Mac connection, connect the iPhone directly to the Mac with a known-good USB cable, not through a hub, and make sure the iPhone is unlocked. If prompted, tap Trust.

If the Mac still doesn’t recognize it and the update still can’t be verified over Wi-Fi, I’d contact Apple Support rather than restore the iPhone. A restore erases the device, so make sure you have a current backup before considering that.
