Till today quasi all carpenters, carpenter-joiner, cabinet maker, wood workers etc... in the world use the SketchUp prog! ;)
Alas the last free version on local computer is not yet existing from a month only "free online" and with no possibility to use plugins!!!
But you can always download the previous 2017 version Make (Free) local for computer! (so using Plugins !!! ) https://www.sketchup.com/fr/download/all
(of course for a pro use you must buy the Pro Version! But for training that is perfect!
Of course learning Moi is also perfect because it's the "SketchUp" of the Nurbs! :)
