Help choosing tire for 700 Grizz.

Be playing around with the idea of getting larger tires for mine. Thinking about some 27 or 28" Zillas on 14" rims. Just worried this might be alittle too much tire. This tire was suggested to me by a buddie that rides a lot.
We mostly ride trails with light mud and water. Don’t like water over the tires, try to keep it under the floorboards really. Ride in some sand also but I’d say 90% of the time its just dry dirt trails. To be honest to stock tires do the job most of the time. Just wanting something more aggressive and taller for when I need it.
Before I buy what other tires should I look at? To be honest my son has been on me about getting him some tires. He just came home with straight A’s. Thinking about surprising him.
