QRP Labs has a bunch of cool projects (https://qrp-labs.com/qcx.html). CW is something I haven't learned yet, but is pretty attractive for what it can do, how far it can reach on low power.
Thanks! It definitely seems popular on the subreddit. Totally agree, CW seems attractive given the possible range, and also being able to clock up contacts while avoiding awkward political chitchat I often hear.
