The golden “survey” trophies will be the biggest grind in the endgame, they require you to find all “collectibles” in each region (all xenogylphs, all scout logs). But the problem is that the game is randomly generated and most of the collectibles are randomly generated too. Different collectibles spawn after each death, so you will need to replay the biomes a lot to find everything and need to get a bit lucky that the stuff you have left spawns. It can spawn the same xenoglyphs again, if you find the same one again it won’t add to your progress. Be prepared for a difficult, random, and grindy platinum.
