Yes, lets stick to a "normal" glibc based distribution.

I think Fedora is the outlier here, Debian is similar to Ubuntu:

docker image ls debian:12.2\*
REPOSITORY   TAG         IMAGE ID       CREATED       SIZE
debian       12.2-slim   31d5e503c34f   2 weeks ago   74.8MB
debian       12.2        0ce03c8a15ec   2 weeks ago   117MB

Given that we already use Debian for the "CI" container, it IMHO makes
sense to use it here as well.
