Hello and welcome to the Cafe. Im sure with your experience your fit well with C4D. I would not try to add any render engines or plugins just yet, get used to what C4D can offer as it can easy do everything in the link shown. Coming from 2D to 3D technically will have some new challenges, but these can be fun too.
Modeling will be the first port of call, so spend some time learning the basics, there is loads of good training out there, and some very talented people here to help.
In order to light up edges of objects that would otherwise appear as a hard edge is in fact not as hard edge as many think, it has a slight bevel, without it 3d objects can look very flat and basic where edges do not catch the light. Although booles will be handy at times to make easy holes, many turn to them before looking for a better correct way to model it, so always try modeling rather than turn first to booles.
You will want to have nice materials to look like plastics, glass, rubber. This is where your need to learn about materials and how to control reflection, refraction, traperent, and translucent properties, metals will also be part of this. Lighting will make or break a render so digging into some basic photography lighting will help a great deal, but often a simple 3 point light will be fine.
Pick a tutorial that is project based where you model, apply materials lighting e.c.t. Il did about and look for some links to start you off.
