I always skip trailblazer III right now. Maybe the ZOC ignore could be on TRIII?
My default with pathfinders is almost always Trail I, II -> sight/movement. My goal with my pathfinder is to explore my continent ASAP and then hit the ocean and, if possible, find the rest of the world. Finding CSs and other civs as early as possible is really helpful- cheaper techs, more quests, etc. High mobility + sight accomplishes that goal the fastest.
The obvious caveat is that your pathfinder can't explore anything if he's dead which should be an argument for survivalism. However, Trail II ignoring ZoC means you don't really get hit by barbarians anymore if you're somewhat careful and once you tack on sight/movement promotions it becomes trivial to not die. The result is that Trail I,II -> sight/movement explores the fastest, promotes the fastest, and keeps your pathfinder alive arguably the best past the very early game.
I suppose the other argument for survivalism would be if you're using your pathfinder more for early combat, in which case more CS and healing while positioned to disrupt enemy ZoC would be better than more mobility most likely. I personally just so rarely use a pathfinder that way when finding more CSs/civs seems so much more important.
The only time I've found myself getting survivalism early is if I'm slow to get an initial warrior out and I'm getting badly harassed by barbarians. In those situations my pathfinder is likely perched in a defensive spot next to my capital taking hits from barbarians while fortified at which point the CS bonus from survivalism is helpful (though the healing outside of friendly territory isn't).
Given that the player will now start with a warrior there will be a much smaller chance of the above happening so I will probably lean even more heavily into Trail I,II -> sight/ movement. I think it's just the stronger/faster/better path.
Having said all that, I think moving the "ignore ZoC" aspect of the Trail line to Trail III would at least give me a little more pause. Your pathfinder would have a much higher chance of getting trapped and killed. It might make survivalism more attractive as a slower but safer path. I'd still probably go Trail first, though.
