Innsbruck to Bern later this month

Hey all!
I am planning a 5 day trip from Innsbruck to Bern. Would love to hear your recomendations what places should I visit and what routes to take.
Austria and Switzerland have stunning topography so it's hard for me to decide where to go as I've never been to that area of Alps.

I preffer smaller roads and I ride a gravel bike with rear panniers so rough gravel is not my friend.
All suggestions are appreciated.

Thank you
