Definitely not for a NEIPA. I would use this thought for a Kolsch or Pilsner but definitely not for something like what the OP is looking to brew.
Step 6 - Please don't stir. I would not touch the cooling wort with anything at this point. Get to under 100f as soon as possible to reduce DMS, but you also don't want to risk contamination.
Step 8 - If you don't have a ball valve to transfer beer from kettle to fermenter, I would dump everything (or almost everything) into the fermenter. No need to use siphon and hop spider. Another way to risk unnecessary contamination.
I use this after a few days of primary fermentation, so I can cold crash and not suck in O2 and Star San:

Everything else looks ok, but like
@mashpaddled says, you're overthinking it. No need to overcomplicate things as a novice brewer. Heck, I'm 6 years in, and I still feel like a novice. But I've brewed NEIPA more than any other style, and I'd like to think I make a good one. I still remove the lid from my fermenter to dry hop and auto siphon into my keg. Never been a victim of oxidation, but I will be moving to closed transfers soon.
