The only default things to do with coke are sink it or burn it in a coal plant. Or vehicle fuel I guess. The other uses are all alt. recipes.
Super long belts do have 2 game engine issues afaik. One is that items on belts are tracked as individual entities, but vehicle inventories aren't. Eventually more entities = more lag, but its many thousands before its an issue. The other is that anywhere with a belt-to-belt connection loses a tiny bit of throughput. If you notice items don't quite mesh together where belt sections meet, that actually has an effect over the long run. Mind you, its only on maxed out belts, and its like 0.1% per connection.
Mostly I'd say its a matter of scale. Trains take up tons of space and are a pain to build, but once you start to build a network, I feel like it becomes easier to keep adding to that instead of building more belts. In other words, building from A to B is more work than it needs to be, but then building B to C is less work than building A to C. Plus trains carry items, power, and you. Being able to hop in a train and autopilot to anywhere is super handy.
This is what that last save looked like. Started in the green circled areas, and that has most of the basics for the first few tiers. There, trains are a bit of overkill. But the yellow areas are where all the other resources are to finish the game, and at a certain point bringing that together without trains is difficult.
Are trains just for fun/diversity of logistics? When I played last year I never got one operational because when I started building my first one I realised that they take up too much space, and then I also realised that its easier and faster to just use stacked conveyors.
