Indeed, it’s a bit more complex setup, you won’t be able to boot without initramfs. But in certain cases (e.g. encryption or partitions spanning multiple devices) it is very useful.
A lot of distros default to booting with an initramfs or initrd by default, anyway. If only because you can set up an encrypted drive at installation time, so may as well have it but not need it rather than the reverse.
About lvm though, experiment with it before jumping in with your daily driver.
