I don’t have or want ‘serious’,
but I would seek out OTR (old time radio)
the comedy was so doggone good back then.
so were the dramas and mysteries.
Sirius-XM has such a channel..channel 148. I've had SXM for years and it is a delight. So much content besides music. I would recommend it highly. Use the app on your phone with some nice bluetooth speakers like these and enjoy.
Sooner...all the things you list are a available on SXM. And then some.
XM148 is one of the channels I listen to.
Our Miss Brooks is probably my favorite radio comedy.
