Car seat recommendations for a 5 year old??

My oldest daughter just turned 5 and is still in a five point harness car seat.. I would like to keep her in the five point harness seat for at least 1 more year before switching to a high back booster.. She's had the same seat for 4 years now and unfortunately needs a new seat now due to that one no longer being usable. It's the graco nautilus 3 in 1 car seat.. Should I just buy the same seat or do you have any better recommendations?

Shes 5 and she is 38 pounds and 3 ft tall.
