UL 4.5ft spinning rod or 7ft l rod for crappie, bluegill, perch etc

Looking to get into fishing for this species of fish. I have a 4.5ft ul rod but I'm not sure if it's what's best for my fishing needs/style. I fish from both shore and kayak/boat and I would be using zman micro wormz, Johnson 2" paddle tails, mini spinner baits, inline spinner baits. Rebel crickhoppers and strike king bitzy minnow cranks just to name a few.

What do you guys think?

Also what line would you run? I run braid to fluro on my bass rod
