That's the behaviour I would expect for gnutls versions 3.6.2 and
earlier (because gnutls only started supporting TLS1.3 at version
3.6.3).  But you said

so that seems a little strange.  Does libgnutls-version have the 30605
value?  Can you also show the output from

    ldd $(which emacs) | grep gnutls
