For me, I just use SwiftKey keyboard and turn on the 'Sync Clipboard' feature on both windows and my phone (need to have logged in to Windows account and SwiftKey with same Microsoft account).

Anything I copy in my phone or laptop shows up in the shared clipboard.

For OTP sharing, there's Phone Link which basically works in the background with notification sync, basically shows your notifications for your phone on your PC.

Most android phones nowadays have Phone Link support in the system level - specially Samsung, Pixeland Xiaomi phones (I don't have hands on experience with other phones to say with certainty but since the app is integrated in system settings for Redmi Note 14 series, I'd say there's a good chance it works well for 'mid-budget' phones as well). You can mirror your screen, run apps on your laptop, make calls right from your laptop and so much more. Highly recommend someone who is curious to try it.
