Changing the /etc/resolv.conf/etc/resolv.conf link to /run/systemd/resolve/resolv.conf/run/systemd/resolve/resolv.conf and listing the DNS in /etc/systemd/network/foo.network/etc/systemd/network/foo.network and in /etc/systemd/resolved.conf/etc/systemd/resolved.conf made it so that the global and NIC settings listed by resolvectl point to 8.8.8.8 and succesfully resolve.
