More pictures and changes! I ended up returning bottom the intake NF-S12A fan and swapped it for the extra NF-A15 fan that came with NH-D15. The NF-A15 is a 140mm fan with 120mm mounting holes and performs slightly better than the NF-S12A which is a 120mm fan.
I also ended up trying a thermal pad swap on the Strix x570-I board. My first attempt was with the leftover 2.0mm Thermal Grizzly Minus Pad 8 I used for the rear NVME. This pad was thicker than the stock one and ended up being 1-2C hotter. I later tried a 1.0mm Fujipoly Ultra Extreme XR-m Thermal Pad that appears to be 3-5C cooler than the stock thermal pad.
