RealMac, makers of RapidWeaver, hosts a gallery where you can see some of the sites that can be built using RW.
There are also many videos online introducing you to the software.
Depending on your learning style, you might find it best to jump in, create a few dummy pages, experiment with the Themes that come with RW.
Blogs (e.g. Typed integration) are not hard to do.
One of RW’s great strengths is that - at least to make a really good start - you can actually drag and drop many of your page elements. Particularly with Stacks.
Don’t be afraid to come here and ask questions… we’re all learners in one way or another. Good luck!
