An admin rule that's at least 40 years old states: Never update to even version numbers.
sandworm and bookworm are (old)stable candidates for the next years.
If you want, you can use new kernels with the kernel plugin and backports. It will take at least until version 13.2 for the Debian software ecosystem to catch up. And the benefit is likely to be minimal compared to the effort.
omv is more dependent on other packages than on Debian. Salt, for example. One of the things I'd prefer to see more horizontal expansion of omv, for example, toward cloud and cluster administration. That's 1,000 times more useful than Trixie will ever offer, compared to Bookworm.
Another old admin rule says that a system must be at least 50% faster than before you, as a user, even notice it in everyday use. I don't think Trixie has achieved that yet. so no rush!
