I run a similar setup, with iwd, systemd-networkd and systemd-resolved.
This has been working without problems on my host for for quite a while
now.

Make a copy of your /etc/resolv.conf file, then enable and restart the
systemd-resolved service. Finally link the /etc/resolv.conf file to
either /run/systemd/resolve/resolv.conf or
/run/systemd/resolve/stub-resolv.conf.  I use the latter:

# ls -l /etc/resolv.conf 
lrwxrwxrwx 1 root root 37 Jun 28  2020 /etc/resolv.conf -> /run/systemd/resolve/stub-resolv.conf

You can configure various settings for the DNS resolver in your
systemd-networkd setting and in /etc/systemd/resolved.conf.

On bookworm you also have the resolvectl tool, which helps debugging DNS
issues.
