https://www.phoronix.com/news/Debian-12-Bookworm-Install-RC4 LVM on LUKS on RAID. That is my (and many other's) favorite setup. I used this on my libvirt-based workstation: https://git.plantroon.com/plantroon/fai-configspace/src/branch/master/disk_config/LVM_LUKS_RAID and manual setup on my libreboot laptop, where I didn't even need the boot partition. Very happy to see it in Debian installer!
