New to blender

Hello, i am a fresh grad architect who uses rhino, grasshopper + enscape for most of the work i always had a huge interest in blender…followed some tutorials here and there but never made a full project in blender i basically want to use blender for modeling & archviz as it is my job then dive deeper into topics i’m interested in like environment modeling.
could use some tips, tuts or any kind of guidance for blender modeling & rendering as i’m used to nurbs modeling…I’m looking for tuts or courses that really explains the process(the how and why) as many tuts you just follow the video without much explanation… thank you

These videos have some nice tips on how to effectively model in Blender non-destructively. Not exactly the extensive source you were looking for (and not exactly focused on archviz), but knowing these tips will be useful.
