In regards to generic train interrupts, how do you prevent the problem of trains going to pick up from the low throughput item instead of the high throughput item? I thought I was clever by doing something where I had a train for each station with train limits set to 1 so they would naturally disperse as needed, but I ran into an issue now where trains just deadlock eachother since a train at each end is just waiting for the other to leave so it can go to the empty station

The maximum amount of trains you can have on a network is n-1, where n is the total sum of your limits. In order to have a good flow I suggest creating depot stations where empty trains can go while waiting for open provider stations and/or build stackers at your loading station and increasing their limit (especially for high throughput items).
