Personally, I actually count all of those examples into abstract lifeforms which you described :D

There's also things like "symbolic" lifeforms like viruses, yeah, they don't live per-se, but they do replicate and go through "choices", but in a more symbolic sense as they are just machines that read out/ execute code.

The way I distinct symbolic lifeforms and abstract lifeforms is that mainly symbolic lifeforms are "machines" that are kind of "inert" in a temporal sense.

Abstract lifeforms are just things that are in a way or other, "living" and can exist on any level of abstraction. Like cells are things that can be replaced, so can be CEO's, or etc.

Symbolic lifeforms can just be forever inert and hope that entropy knocks them to something to activate them, without getting into some hostile enough space that kills them.

Abstract lifeforms on the other hand just eventually run out of juice.
