Yes the way you made it it’s correct. Most of the time I think there is no hacking it, what I’m after is a pleasing result and if I got it then I took the right path.
For the edges glowing you’re going to have to check that out, at some point you must have selected them, but either way they are glowing, so they are assigned one way or the other, or maybe there are UV’s there. Check and troubleshoot.
Cycles and Eevee are very different renders. Eevee has the glow effect which is probably helping, Cycles doesn’t have it and you’ll have to use post production mostly. Same when ti comes to reflections, on Eevee you have to use irradiance volumens and reflection probes. You’ll get approximations, not 100% equal renders.
You can take the Fundamentals of Lighting and Material and Shading I think it is to see how they each work:
