Bathroom Circuit questions

I'm a DIYer with a pretty good ability to wire up new circuits.

I've gutted my bathroom and have questions about how many circuits I need in the bathroom. I think I might be overdoing it.

I have 2 receptacles on either side of the double sink, 2 receptacles under the sink, multiple receptacles on the walls with about 4 foot spacings, receptacle for jacuzzi tub, circuit for towel warmer plus a couple circuits for lights + bathroom exhaust fans.

1. I'm protecting the lighting circuits via wiring them first to a GFCI receptacle located by the load panel. Lighting circuits go into GFCI wall mounted receptacle, then onto the load center. I'm using this to GFCI protect my lighting circuits. I was going to protect this with a standard breaker, but now I'm told this needs to be additionally protected with an Arc-fault breaker, is this correct?.

2. I think I mis-read the code about dedicated circuits for the bathroom. I intepreted this as dedicated circuit per recptacle, but I think this is way over the code requirements. So, this is what I'm thinking, all with GFCI receptacles simply to keep my wife from blowing circuits with her hair dryer + hot comb in the same receptacle:

Circuit #1 - 1 Left side + 1 right side sink receptacles + undersink receptacle + 1/2 wall receptacles (GFCI in each receptacle box, some with LED night lights)
Circuit #2 - 1 Left side + 1 right side sink receptacles + undersink receptacle + 1/2 wall receptacles (GFCI in each receptacle box, some with LED night lights)
Circuit #3 - Jacuzzi (GFCI only)
Circuit #4 - Towel Warmer (GFCI only)
Circuit #5 - 1/2 lights + 1st bathroom fan (Arc fault + GFCI)
Circuit #6 - 1/2 lights + 2nd/3rd bathroom Fan (Arc Fault + GFCI)
Circuit #7 - Radiant Heating (Arc Fault + GFCI)

Is this reasonable or not?

Thanks,
