St Augustine area july

Made camping reservations last two weeks of July at St Augustine. Bringing Jon boat with too. Going to be doing a lot of saltwater stuff beach and boat.
would it be worth hitting crescent lake or the river in welaka? If so would jigging be good enough I’m trying to travel light with gear
I remember getting bass bear creek in welaka when it was hot also that was about the time I got frustrated with bass and began crapoie only trips
Boat is 16ft and has 25 hp motor. I have a portable live scope

it’s been 12 years since I did saltwater any tips for that or pages to check I don’t care what I catch

I’m making trip from Illinois. I figure beach weather would be good. Also my newest dog has not been to fountain of youth park or beach while the others have made multiple trips
