So, here is what my system does and how it is set up:

In TTY:
-
Both, ping -c 5 fritz.box
and ping -c 5 192.168.150.1
(ip address of fritz.box) work.
-
ping -c 5 ulm.de
does not respond. ping -c5 20.103.215.75
(ip address of ulm.de) works - ulm.de is an example for whatever url).
-
pinging of any ip address works
-
No DNS resolving works other than fritz.box
host dns.fritz.box (dns over TLS servers in fritz.box)
dns.fritz.box has address 5.9.164.112
dns.fritz.box has address 185.95.218.42
dns.fritz.box has address 194.242.2.2
dns.fritz.box has address 78.46.244.143
dns.fritz.box has address 185.95.218.43
dns.fritz.box has address 89.233.43.71
In Plasma 6.4:
All network and dns resolving works

cat /etc/resolv.conf (systemd-resolved, stub)
This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8).
Do not edit.
This file might be symlinked as /etc/resolv.conf. If you’re looking at
/etc/resolv.conf and seeing this text, you have followed the symlink.
This is a dynamic resolv.conf file for connecting local clients to the
internal DNS stub resolver of systemd-resolved. This file lists all
configured search domains.
Run “resolvectl status” to see details about the uplink DNS servers
currently in use.
Third party programs should typically not access this file directly, but only
through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
different way, replace this symlink by a static file or a different symlink.
See man:systemd-resolved.service(8) for details about the supported modes of
operation for /etc/resolv.conf.
