The Ruby on rails channel on YouTube has a playlist explaining all the new components of rails 8 called rails 8 unpacked. Things like solid queue/cache and propshaft.
The Polished Ruby book is also really good IMHO[2].

It's the book I learned originally Rails with more years ago than I care to remember (pre version 1!).
Sustainable Rails is really more about how build bigger projects over the longer term.
i.e. good practice for reducing the churn on model files when you have a larger teams or how to do things with a miniumum of external dependencies.
It's great stuff but you can probably pick that up later if you want to.
BTW I just saw this in browser tutorial from learning Rails[1]. I've not run fully through it but it looks really promising to me.
