Since you sound pretty new to the game I’ll give you my opinion on where to start. I would get a spinning rod/ reel and I would certainly buy a graphite rod over a glass one. The feel of graphite can’t be matched and will improve your catch once you figure out what it helps you feel. Prices on graphite rods have come way down in recent years and very affordable, depending on which brand you choose. I like and own some G. Loomis and St Croix rods but they can get up there in price. You will be able to find one in your price range from the many choices of other brands.
Matching the rod/reel to a particular fish is key. Like golf clubs and wrenches as examples, there are different tools for different jobs. Fortunately Large mouth bass and many salt water southern coastal fish like redfish, trout and snook can be taken of the same rod. Since you said primarily salt I would get one with a little more backbone and a stiffer tip for hook sets in harder mouths and horsing a 20lb snook or redfish.
Check out some Florida fishing forums for what the rods of choice in your price range for your quarry. Here’s a site I've purchased from over the years. Prices are good and they are well know. Good luck and Catch em up!
