Best you can do is build a high end desktop at home and access it remotely with any laptop you desire. The laptop performance then becomes mostly irrelevant (even the OS is less relevant) and by using modern game streaming protocols you can actually get great image quality, low latency and 60+ fps. Though, optimizing it for low bandwidth is still a chore.

Have that desktop be reachable with SSH for all your CLI and sys admin needs, use sunshine/moonlight for the remote streaming and tailscale for securing and making sunshine globally available.
