It's 1/4-1 oz lure weight, 10-20 lb line weight.

Is this strictly a worm/jig rod, swimjigs????

Can this be used for frogs & heavier crankbaits/jerkbaits?  How about under 5" swimbait types like Shadalicious???

It's quite the opposite of what you would want for any crankbait.  Jigs, soft plastics, basstrix type baits, buzzbaits, or even a c-rig.  That 6'9" is pretty stout.
