Previously used a HP 14-ck2010tu for gaming (lol)

Running 144hz 1080p

Planning to buy during Black Friday/Cyber Monday

My main question is whether the extra GHz is worth going from the i5-12400F to i5-12600 for $100 and if a USB WIFI adapter would be more cost effective.

If that's the plan wait until November before you even consider making a parts list. AMD is announcing new CPUs on Monday (we'll likely get teasers for next gen GPUs at the same time), Intel is announcing new CPUs late September, AMD is supposed to release RX 7000 series GPUs in October/November. The only people not releasing next gen stuff by then is Nvidia. Stuff will change so much by then that whatever you're planning on buying won't really make sense at that point.

Not really. Performance is within 5% of each other in most tasks, if you're not using the iGPU there isn't really a point.
