you'll have to shop around to get a saddle that suits your sit bone width and the particular geometry of your bike frame.
its like bike makers collectively forgot how to make bikes some time in the late 1970s.
and by the 1990s comfortable bike designs no longer exist, everything got given up for a bit more speed.
I recommend to try out some 1980s ATBs and 1960s gentlemans and touring bikes, I found them more comfortable than any modern bike.
