I don't think Inter will have a chance to beat City's dominance in midfield. The most reasonable solution is to play the bus with the hope of counterattacks. If you block all the zones before your own penalty area, then despite the overwhelming possession of the ball, City will have few chances - it worked with Barcelona (that Barcelona of the tiki-taka times) and can work with City. In open football, Inter has no chance.
I agree with you, normally Inter has no chance of winning this match. Maybe if the luck is on their side and their opponent makes a mistake, they can score a goal. Scoring goals with counterattack will be one of the best options for them.
At the end of the match, I think Manchester City will win. It will be a pleasant final match, I hope we will watch many goals
I'm not sure that it will be a beautiful and interesting match. Maybe City will be lucky and can score an early goal - then we will see them an easy victory, maybe Inter will be lucky and they will keep a draw (or a minimal advantage obtained in a counterattack) until the very final whistle - then it will be a grueling struggle. In both cases, I don't see anything interesting. In any case, I do not plan to watch the game, at most I will check the text broadcast from time to time.
