C2 has no future, move to C3.
Cordova CLI and PhoneGap, cocoon.io seems to be dead.
For Admob integration you can try Enhance service:
https://enhance.co/
but the problem is when you use enhance the apk became very big and that not good. and i don't know if its a trust source or not
i have a question its possible to import construct 2 template to construct 3 ? and all plugins related to construct 2 will work in construt 3 ? and its easy to go from construct 2 to construct 3 ?
and another question : if you work in ios . and you use construct 3 to publish game to IOS . you need make or not ? and thank you
