Replacement for a Lenovo Legion

My friend's teenager has a Legion Y530 with a 15" screen, 8th gen i7 and a NVIDIA GTX 1050, with a broken power button.

The kiddo will need a (high) school laptop soon though, so sturdiness and reliability is more of a concern than gaming, thus the current thought is to find a replacement rather than fix this one.

Obviously I'm fond of ThinkPads, and they're readily available, so that's where my mind is going.

Comparing this Legion with my T480, the biggest visible difference, aside of the GPU, is the screen. The Legion screen is not great, but still a huge improvement.

So the idea is to find a TP with a nice enough screen and at least basic gaming capability, either with a dGPU of some better iGPU.

The budget is not yet determined aside of "as cheap as possible" and "best bang for the buck". So probably some vintage.

Screen size is also not completely decided, but 14" probably makes more sense for portability.

I'm seeing T14s G1 AMD with Ryzen 5 4650U + 16GB + 512GB for under 300 € (Europe), what do you guys think? Is there anything where you don't have to pay much more and get something significantly better?

Ed: And for 15", I'm looking at L15 G1 AMD, with what seems to be an average office screen at best.

Thanks!
