What reel should I get?

Just got a 7 ft medium heavy fast 1/2 oz-1 1/2 oz 12-20 lb line casting rod. I’m gonna be using it for inshore saltwater fishing along the east coast of the US. Jersey down to South Carolina. I have a penn squall 200 size low profile bait caster that fits it good but I’m not sure if it should get a 300 size for it. Anyone have any good suggestions for a good 300 size saltwater baitcaster? Or reasons I should go up to 300 instead of a 200? Or vice versa. Let me know.
