I think you should use the versioned library, yes. If the soname changes
then that indicates that binary compatibility has been broken, and
dlopen()ing the newer library from a program compiled to expect the
older library may be unsafe.

That depends on the library. Ideally, the upstream maintainer of the
library should be in control of sonames.
