If you are running tor over systemd, you will also need to set
NoNewPrivileges=no in /lib/systemd/system/tor at default.service and
/lib/systemd/system/tor at .service and then run systemctl daemon-reload.
This issue was first documented in <https://bugs.torproject.org/18356>.

If you are not running tor over systemd, setcap should suffice.  I just
tested it on Debian 10 and I managed to set up an obfs4 bridge on port
123.

Cheers,
