i've been to all except Jalama. lived for 17 years in Ventura County and never got around to going there.
one thing, Ocean Mesa in El Cap, is on the other side of 101, from the beach. as far as i know, they don't have any beach/oceanfront campsites.
they do have oceanVIEW campsites.
you'd have to pay to go park at El Cap State Beach or ride a bike or walk past the SB kiosk to get to the beach.
