Which type of RPi2? There is more than one.

I've access to:

a RPi2B v1.1 (Cortex-A7, so armv7 only)
and:
a RPi2B v1.2 (Cortex-A72, so aarch64 but also capable of armv7 use)

RPi3B variants are also Cortex-A72 based, so aarch64, but are also
armv7 capable. (I've access to a RPi3B as well.) Basically a
RPi2B v1.2 is a variant of the RPi3B.

As of the RPi4B's the RPi* folks quit trying to allow booting as
armv7. But in FreeBSD you can chroot into a armv7 world on a RPi4B,
for example. (Also on: RPi3B or RPi2B v1.2 booted as aarch64.)

You can build armv7 ports on a RPi4B via poudriere, no quemu
involved. The same for RPi3B booted as aarch64. The same for RPi2B
v1.2 booted as aarch64.
