OnShape is my go-to. It's what I taught my students when I was a TA for an introductory engineering class at college, and they could pick it up in about a day.
Can do just about anything a "professional" cad suite does, but it's free, works in a browser, and is generally so much better designed so you don't have to fight against the UI to get anything done.
I'm also team onshape. I have a powerful desktop, but I still end up doing CAD from the couch on my 6-year-old Chromebook, so onshape is a champ for that. It's also nice for collaborating, which I do when working on bigger projects with my fiancee.
I got started with it entirely from the tutorials provided by Onshape itself. The learning curve was a lot less steep than I expected.
