Blender doesn't use the nice boundary representations that you might be familiar with from Fusion 360 or Solidworks. Everything in Blender is "bag of triangles/quads," so it's lower level than what you may be used to. Getting good CAD-like results requires keeping this in mind. There are addons that are starting to address this. SolverSpace has a blender addon, for example. What do you want to build? If you're not making CAD parts, the story is much different for artistic / game engine / character or environment design. I strongly recommend checking out Blender and noodling around. If you're intimidated, the only cost is time, which is offset by the pleasure of learning something new.
