Finishing deck: what to caulk?

Putting the finishing touches on my deck and wondering how much to caulk?
Do you caulk the white base trim on the post to the post and deck?
Do you caulk the post cap?
Do you caulk any of the railing parts? or where it meets the post?

You shouldn't need any caulking.

Pics could be helpful but generally you don't do much if any caulking on a deck or it's railing.

Only thing I caulked I had two composite finish boards on the rim joist where it went around an outside corner that had a minimal gap and I used some exterior Quad caulk to fill the gap.

In general nothing needs to be caulked unless like above it's aesthetic!
