There is no such thing as an ideal diameter: It depends on what you're trying to do.
That said, sounds like you might like .6 mm based on what you said.
Layer adhesion should be fine with any. In theory, it should be better the thicker you go, but whenever you change nozzles, you need to readjust everything.
Personally, I just stick with .4 almost always because I'm lazy and it's an OK enough balance of detail and speed.
. 6 is my favorite size
A lot of people really seem to like that one, little faster than .4 but better detail than the extra thicc stuff.
