getting close to installing my new flue setup. I was wondering if there was a "go-to" caulk/silicone adhesive for sealing the top plate to the crown of the chimney. In this case it will actually be a transition plate transitioning from flex liner to class A pipe. I'm going to be installing tapcon screws, into the crown but would like to make sure the actual sealant I use is up to the task.

I've used GE Silicone II with good success. The top cap stayed stuck on during an earthquake, while the chimney below it rotated 45º. Make sure surfaces are clean and dust free.
I thought I had remembered reading a post of yours along those lines. Thank you for the suggestion 👍. @begreen did you use this specific one (https://gesealants.com/products/concrete-silicone-2-sealant/2708922)?
Back then there was only GE Silicone II, it was relatively new on the market at the time. They sold it as all-purpose and it only came in clear. My guess is that this is now called their door and window product.
I'm not sure which of their specialty versions would be best now and whether there is a distinct difference other than color.
