I was wondering if there was any oils that typically were higher in dispersents for the break in period of a new engine. Does it even matter if you're doing frequent oil changes during break in? I figure there's a lot of wear materials that will need to be suspended for the first 5,000 miles or so.

I guess I should clarify. I wasn't expecting anyone to go 5,000 miles on the initial break in oil. I just meant 5,000 miles as a general point when break-in wear metals start to decrease (I could be wrong about that exact number). I would imagine something more along the lines of 500 ,1500, 3000, and 5000 mile changes.
I was more just curious about how much impact dispersants might have on wear during break in.

As long as you're changing at the intervals above you'll be good to go. At those intervals your oil isn't depleted of dispersants but rather removing the high wear metals that can cause extra wear on components of the engine.
I think all the brands of Break-In oil will do fine. I use Amsoil..but any of them are designed to do the job. I break in engines on a dyno but in real world driving I'd change it after a few hundred miles. Don't let the engine sit for very long as most break-in oils do NOT have corrosion protection.
Depending on the engine and type of driving the intervals after that can vary. My street rod customers I recommend changing at the beginning AND end of season if they're using conventional oil. These engines usually run rich and can get fuel dilution. Changing at the end of the season gets that stuff out of there. Then sitting all winter the oil can oxidize. Synthetics will avoid that issue.
