But the same classical systematic theology textbooks which explain how/why/what is meant by “in an analogous way” go on to provide an outline which includes the points and “standard proof texts” which I mentioned in the very brief summary above. My academic career was more exegesis than systematics but I can attest that this is pretty standard stuff. And because William Lane Craig was mentioned I should also add that he has a seven year systematic theology video series (with transcripts) available for free on his ReasonableFaith.org website. It is in his Defenders Podcast series (there’s three of them because when he finishes one series he starts a whole 'nother one.) I know it is somewhere in his Doctrine of God portion of the outline. One can probably find it easily with a keywords search of “Divine Aseity.” I can recall some of the lectures where he talked about what it means for God to want/desire/will various things.
And yes, at age 70 I have a neuromuscular disease (similar in symptoms to multiple sclerosis) which introduces spelling errors including repeated characters—most of which get fixed by my auto-spell check tool, but I have discovered just now that aseity is not in its vocabulary. I see that it did manage to flag the misspelled word as unknown but my vision limitations cause me to miss things. (Yes, such as my not seeing the notorious “red dot” in the middle of some of my cartoon images until @misterme987 pointed them out. That one appears to be a sometimes artifact of the screen capture software I use. Sometimes it will clear with a Windows reboot and sometimes not.) I read with just one eye and the field of vision is small.
