TL;DR: If a tool or component is missing in the ARM64 flavour, it should work okay thanks to the Prism emulation.

Adding just a couple of notes as a long-time user of Arduino tools on Windows for ARM (via Parallels on Mac with Apple Silicon).

Arduino IDE, Arduino CLI, and related tools built for x86/amd64 work out of the box on Windows for ARM thanks to the Prism emulation platform (see more https://learn.microsoft.com/en-us/windows/arm/apps-on-arm-x86-emulation). I've been using them in various scenarios, and even the PLC IDE works seamlessly (based on ArduinoCore-mbed, the arduino-cli, and Sketch profiles).

There is the Prism emulation layer that guarantees compatibility.
