Agreed, standard commercial radio is not great these days. So many ads, and playlists of the same old stuff on repeat.
That's the main reason I still love & listen to CKUA. It's great for finding music I've never heard before, both new and "new to me", selected by people with great musical knowledge & taste rather than an algorithm or based on popularity. A good adjective to describe it would be "eclectic".
Many communities have similar stations, it's worth checking out in your local area if anything like it exists. Public, community run radio can still be great.
