It’s really simpler than it sounds, I’ve used it a few times myself. You can also use an #Ubuntu iso to execute this process after booting from it to ensure the 16GB partition is not in use when trying to copy it.

Sounds like you have a specific set of needs. Changing OSes can be like moving homes or learning to fly a new airplane type. It’ll takes time & trial/error to get everything dialed in just right.
Most people I’ve seen have success with debian-based LTS variants. Debian/Ubuntu /Mint. Long-Term-Support = 5 years or more of consistency. There’s broad h/w support for both Debian and rpm-based linuxes, so either flavor would work, but unsure if rpm-based have LTS options.
