My employer has similar plans. Ubuntu 24.04 will be the last Ubuntu release in use for production. Once the support period ends, we are migrating to NixOS.
So you're moving from a distro that's being wrecked by ideologically-driven decisions, to one that is almost entirely ideologically motivated and notable for internal drama. Great choice, best of luck.
Still wouldn't switch to another distro anytime soon, you know, sunk cost fallacy and all that.
