If you need a good reference point for exploring a more modern Pokemon world, use "A Beginner's Guide To Pokemon" by Thanos6 on Fanfiction. It is a breath of fresh air, and it has great descriptions that an aspiring author can bounce their craft off of.
Another good reference for Pokemon is the story "Sacrifice and Subjugation" by MetalDragon. This story is a great reference because it shows that Pokemon won't just listen to you after capture and the trainer must work towards earning their respect/devotion to use them adequately. It also brings up a great concept of the Shift that I think is super unique and something to be expanded upon. This story also is very good with its pacing in regards to story and training, definitely look at it to get an adequate pace to your story.
