This is awesome!! Is CheerpX able to run the JITed code generated from node/v8 as well?

Or said in other way: is the node binary compiled with v8 in interpreted mode, or does it support the v8 JIT?

This is a surprisingly common question. What you see is a standard node.js/V8 package from Ubuntu with no modification at all. V8 will emit JIT x86 code that will be then further JITted into Wasm if hot enough.
