This brings me a lot of joy.
I'd steer clear of getting him anything with a floating trem. There's nothing more discouraging than a guitar that requires a lot of work to re-string, tune, detune to drop d, all that.
I think any standard Strat would be perfect. Squier or Mexican Fender. Most are routed HSS, so if you have a harvested humbucker laying around (don't we all?), you can get a HSS pickguard and install it.
That way, not only does he get a versatile guitar that brings the rock, but he gets a platform that can evolve with him.
The guitar I'm playing the most these days is the body from my first guitar (Squier Affinity Strat made in China) with literally everything else replaced over the years with aftermarket parts.
