So about 450 pixels? (110'×12"÷3"=440)

Im guessing that running 12v you could likely get away with 4 total injection points. Two internal injection points and ones on each end. But there's more to it than that. See where you can inject power at natural breaks in your roofline. Injecting power on strings is WAY easier than strips.

Yeah, my napkin math came out to be 425. I bought 500 to be safe.

My box will be at pixel 210 so I’ll have to run power/data to the beginning anyways. It’s over the garage so it should be easy.

On the other end, I have the option of putting a 2nd psu if I really want to. While building the house, I at least had the foresight so put outlets in the eaves for Christmas lights so that’s how I plan to power everything. These outlets just so happen to be at #210 and the very end of my run. At this point I’m just trying to figure out if it’s easier to run power to the very end or put the 2nd psu there.
