English question - ".that being said, ..."

It's like when you're adding onto something

Like

And then he told me that gummy hot dogs were the best candy, can you believe it?! That being said, what's your favorite candy?

to add on to what the people said above, it can also be added to a sentence when you're adding a negative or "countering" statement to a positive one.

eg: "this medication is good for weight loss, that being said, it may not be beneficial for people your weight."

"there are many upsides to moving to town A, that being said, a lot of areas are still in construction and unfinished."

i have almost only seen it used in this context^
