Small 5 yr old - looking for car seat recommendations

My daughter is 5 yrs old, 31lbs and 38 inches tall. She is currently in a Nuna Rava, however, we were in a minor car accident and need to replace it. Because of this, I was looking at car seats that can transition into booster seats later. I was considering the Nuna Lumn but the price is off-putting. However, we may still be using this for several years considering her size.

Additionally, she has noticed at school pick up that other kids her age are in booster seats and has asked when she can switch. Obviously, she has a few years before we are at that stage which is why I liked the Lumn - it has less of a "car seat" appearance to it. She is already sensitive about her size and I am concerned this will get worse when she starts kindergarten.

My question is, does anyone have any recommendations for similar car seats that transition into boosters and have less of a "car seat" appearance? Preferably cheaper than the Lumn!
