I highly recommend onshape these days if you're ok with a web app that makes all your design open source (the pay for private space model has a steep cliff, but for my hobby purposes and open source enthusiasm it's great).
Recently I transitioned to freecad. There was a bit of a learning curve since it is more constraint based than fusion requires.
Once freecad 1.0 came out for prerelease use I started using that instead...it is much improved over the old method. A lot more similar in use to other CAD packages.
I suggest finding a few good tutorials and working through them...it took me a lot less time to learn freecad (for me) than it did to learn fusion...and it removed one more closed step in my mostly opensource toolchain.
I get an embarrassing amount of mileage out of Tinkercad. It's free and incredibly easy to get going with. I keep meaning to take some time and learn a more sophisticated program but the payoff has never offset the speed of delivery that I get with a rough cut using Tinkercad.
