it is impossible for God to lie

[Jim Parker]

My theology is that the Bible is inspired by God only in the sense of communicating spiritual truth.

I don't have a problem with that. It seems to me that's the purpose of the Bible.
2Ti 3:16-17 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.
Scripture is inspired by God and is "profitable", meaning that it provides good instruction in the areas of:
(1) doctrine
(2) reproof
(3) correction
(4) instruction in righteousness
The purpose of the instruction, its goal and desired outcome is:
(1) that the man of God may be complete
(2) that the man of God be thoroughly equipped for every good work

I don’t believe it is even vaguely inerrant “about the events of world history” as the Chicago Statement asserts.

While many events depicted in the Bible are historical (they occurred in an historical context) the Bible is not a history text book.
I believe the Genesis 1:1 through 2:3 is the "genealogy" of the heavens and the earth. It is the standard of ancient near eastern literature to introduce a story with a genealogy. 1:1 -2:3 is that genealogy and the creation story begins at 2:4.
Just my understanding.
If the Chicago Statement is meant to tell me that the heavens and the earth were created in six, 24-hour days, I'm not buying that.

For example, the best (overwhelming) archaeological and historical evidence is that nothing resembling the Exodus occurred or could have occurred; efforts to “salvage” the historicity of the Exodus, like efforts to “salvage” a 6000-year-old earth, are not convincing to me or many others. This being the case, I believe that Exodus 9:20 tells me precisely nothing about the character of God.

Then you missed what Ex 9:20 was communicating.

The Exodus myth communicates profound spiritual truth about God's providential care for his people, but the historical details are from the mind of the Jewish authors.

Many people think that "myth" is a synonym for "fairy tale." A myth is a story that communicates an important truth while "the facts of" history depend on who is writing the history. (That's how we came to have had a "Civil War" and a "War of Northern Aggression" at the same time.)

o you do not get to define for me, any more than I get to define for you, what "the God of the Bible" means.

I didn't define the "God of the Bible" for you.
The Bible does that.

We all think our own "God of the Bible" reflects a more mature or enlightened understanding than other views.

Speak for yourself.
That is not my opinion at all.

We all believe in the "God of our 'belief'" - it cannot be otherwise.

I agree.
