Formatting Internal Dialog

My writer's critique group fell into a debate about the proper formating style for a character's unspoken thoughts, or internal dialog. Some simply wrote them in first-person as a continuation of the narration, with no delineation between the two. Some just added the tag "she thought." The subject came up because, in my manuscript, a character's thoughts are italicized. They wanted to know why I did it that way. My only answer was, "That's how I see it done in books I read." That wasn't a satisfying answer for them, so I did some research.

My first resource was my trusty Chat AI that I use to critique some of my sentence phrasing. In fact, it indirectly answered the questiion before I even asked. I offered it a paragraph to critique, which included one sentence of italicized internal dialog. When I pasted the text for it to evaluate, the italics were lost. But when it regurgitated its critique, it restored the italics! So I had to ask, why? It's response: "Italics are the standard, cleanest, most widely accepted way to format a character’s unspoken first‑person thoughts in modern fiction." Okay, so that's it. Good. But then, it also added: "But there are nuances ...."

Oh, great. The old, "on the one hand ... but then on the other hand ..." dodge. It categorized two kinds of internal dialog.

1. Direct, first‑person style - Italicize this. It's what I used: switching from third-person narration to first-person internal dialog to give the thoughts immediacy. For example: I'll be back soon enough.
2. Free, indirect style - No italics. I use this sometimes, too, when the thoughts aren't intended to be so emphatic, but instead should flow smoothly in the narration. The thoughts remain in the narrator's third-person voice. For example: He would be back soon enough.

Reading other online sources, I see the same rules shown above. But there are other acceptable styles. For third-person POV, the "she thought" tag can be used, with the actual thought either italicized or not. But without italics, the tag must be there. For first-person POV, it's the same, but with "I thought" as the tag. The exception for this POV seems to be that it can be non-italicized and without a tag, free flowing from the narration to thoughts. I suppose that makes some sense, since first-person narration is a bit like one long thought about everything the character sees, hears, and feels.

One rule that does seem set in concrete: internal dialog is never enclosed in quotation marks. It's just too easy to mistake for the spoken word.

From what I gather, my critique-mates aren't about to change their style based upon anything I say. And I don't know if this formatting issue earns demerits in the eyes of agents, editors, or contest judges when a manuscript is evaluated.
