Nice. Yeah, it's easy to get gushy over the latest synth and forget that the native plugins can do a lot for you. I really need to explore The Grid in Bitwig once I've got my current project over and done with. And like you, it saves on a lot of processing power too.
I have had a few people comment on my chord progressions. My approach has always been a very exploratory one. Sit at the keyboard, find a chord I like, then experiment. What happens if I change bass note? Can I keep the left hand the same and change the right hand? What if I just move all the notes up by one? What if I replace this chord with one from a parallel key?
Eventually, the mind's ear senses a shadow of a chord progression in the vague fog of creativity. From there, it's just about finishing the puzzle.
Looking forward to hearing what comes out of your learning!
