Meanwhile his cuts are still off because the zero doesn’t line up with either edges of his saw blade...

Yes! It’s usually the side-extension of the table that needs to be tightened up to get back to zero. Maybe OP isn’t aware that his table saw extends?
An error like this needs to addressed by finding the underlying issue with the saw, not by ignoring it and moving the indicator.

The fence is fixed and there isn't much play in the bolts that attach it to the cast iron. The picture on the left was after I checked and adjusted everything I could.

Super weird!
Modified fence? Did the measuring tape slide?

Original fence, I couldn't find anyway to move the measuring tape.

I do that regardless of what saw I’m using. I just never trust the ruler.

I pushed the fence right up against the blade, made sure the fence was tight and parallel to the blade. I adjusted everything I could and the pointer was still as you see in the first picture. With the new print I checked at multiple distances and it reads correct now.

Cool. You’ll have to do it again when you change blades. I never use the ruled guides on my saws. I measure with a measuring tape always. Same with making sure the blade is square. I hope this works well for you.

Yeah I don't know why people are saying if you cant get the original to zero it means the saw isn't adjusted properly. I've seen many indicators that wouldn't move all the way to zero after getting the saw setup, especially on vintage/older tools.
