Default Filling gap in block wall

Hi folks,
I've got an exterior block and stucco wall that joins a 2x6 cedar wood frame wall. There is a gap of 1/8" to 3/4" between the two and I'm looking for the best method to fill the gap.
Thought about using some Top and Bond that I have but am looking for other options.

Default ok

I would use a good ,flexible sealant like lexel, or geocel. Stay away from silicons and latex. not enough adhesion with those products.
Also use what is called backer-rod in the gap first,if it fits, it cuts down on the caulk.
The top coat will just shrink and crack again.
Good luck.
