Debian is already noiriously lagging behind latest package versions (that’s how they make it so stable : they freeze all package versions when they release a new version of Debian, and only backport security fixes).
Either your AI was trained before Debian 13 came out, or it is giving you really bad advice. I can’t think of a single good reason to use an older Debian for a fresh install…
I usually have Debian on all my servers for stability, and run almost everything inside containers for convenience. The few things that run directly in Debian are nginx for reverse proxying to container services, fail2ban+firewall, and wireguard for everything that moves data between servers/computers/devices I own
