Embedded covers a wide range of systems. Are we talking about a NAS
box with lots of storage, a WIFI access point, the center console of
your auto, a drone?

In generally, i just run Debian on everything, making use of the
bootloader which is already there, and if needed, adding extra storage
via a USB stick or SD card.
