My advice: Go with Reaper.
It’s just as capable as any DAW, cheaper than most (maybe all), less resource intensive than most, and more customizable than most. Once you get a handle on creating “custom actions” you’ll realize you can make it fit with your workflow very easily.
It doesn’t come with a whole bunch of virtual instruments or samples though, so if that’s what you’re looking for you might try something else, or spend some extra money on 3rd party stuff. And you’ll have the extra money because you didn’t pay $500 for Reaper in the first place!
Audacity is not a full featured DAW as far as I know.
