Help! Need hair/ style/ product advice

So I’ve really been hating my hair lately, I feel like this style is too “teenagery” I’ve had this hair style since I was like 15 and I’m now 20

My hair is SUPER straight and super thick. I mean there is ZERO texture or flow it kinda just flops down into whatever it wants

Theres just no style at all its like a 5 year olds coconut hair style and it feels hopeless

I usually avoid super short cuts because I really don’t have the best jawline but im just looking for general advice, hair style suggestions to ask my barber

I’ve tried it all, texture powder, cutting it short and trying to style it, I’ve gotten a perm before, but it always just goes back to this childish middle part.

I want something more grown up and better groomed. Any advice or hair style suggestions will be greatly appreciated. Thanks everyone🤝
