Pask Makes - Australian wood- and metalworking guy who does the most elaborate and intricate things with absolute chill.
Dashner Design and Restoration - also woodworking, finds old and neglected mid century modern furniture at thrift stores and restores them beautifully.
Maybe tangential but FutureCanoe - meme-y cooking channel, super relatable and relaxing mostly because his voice sounds like existential dread.
I don't think that's universally true, I agree with some other posters here that a big part of enjoying a hobby is the learning process and getting better at it.
Yes, excessive comparison to others and worries about performance and the like are killers for enjoyment, but the pursuit of skill is a major part of a fulfilling hobby for me.
