A bit ignorant of me, but is there nowadays any restriction
on the choice of boot partition?
I don't use LVM (having had some catastrophes several years ago)
and always create a small boot partition among the first 3 partitions:
   sda1 Windows (does MS still require this?
   sda2 /boot
   sda3 swap
   sda4 extended partition
I guess this methodology is probably long extinct?

Nothing keeps you from doing it that way, but many of us have gotten used to (and comfortable with) the abstraction layer possible with LVM. Never had any problem with it, and happen to like it.

With grub and grub2, there is no reason to put /boot in a separate partition. That goes back to the days of LILO, when it could only read the first xx megabytes of a disk drive. Both versions of grub are quite comfortable reaching to the back of a big disk to pull up your /boot files.
