Do you have anything specific you’re targeting?
You can catch some good red fish, black drum and all that with just a simple 3-4oz weight, and a circle hook at the end of a 3ft leader with 1/2 a crab or mullet on the end.
If you’re near any structure like rocks, pier, or something along those lines, just put a small hook in the back of a live shrimp and let it live-line. You’ll get just about anything from spec’s to permit, to flounder, to reds with it. It feels stupid but it’s probably the most effective set up there is.
A 3000-4000 series is all you really need. I am a huge fan of the penn battle’s (reel is awesome, but rod’s not as high of an action as I like). Diawa makes a similar combo that’s also really good for the same price point but has a stiffer rod ($200 ish).
