You're missing boot camp drivers hence no wifi but the fact that it boots into Windows is a very good sign and I don't think the laptop is dead quite yet.
Edit: Conclusion. Your recovery restore was probably broken and you probably had a very broken install. You could probably go ahead and re-install macOS Catalina and go from there. I'm still kinda interested if you wish to part ways with it but can understand if you wish to touch wood and re-install macOS and have your lappy back.
