I have an RCS on order, and I’d like to increase the top speed I can ride at by replacing the cassette (and deulailler if needed) to something like 9-32. Is there a cassette that I’ll work on the stock RCS hub?

It might be easier to go to a 56T chain ring. With pedal assist, you won't miss the minor loss at the low end.

I don't know that they have a cassette with anything smaller than 11.
I hit 34.5mph on my RCS on a slight downhill, and I'm a fat old man. The bike isn't fast enough?

No. Cassettes that offer 9 or 10 tooth cog only work the SRAM XD Drive freehub bodies, not a standard freehub body. The only other small cog cassette is Shimano's Capreo, which only fits on a Capreo hub.

Based on my experience with my CCS higher gearing would be a complete waste on these bikes. The current gearing has me pedalling comfortably in 8th gear up to around ~32 mph, the bike won't provide assistance above ~33.5 mph. When I shift into 9th (52T chainring/ 11T cassette) the pedal cadence is uncomfortably slow at 32 mph and doesn't become reasonable until at least 34-35 mph, (I don't have a cadence sensor but at 32mph I'd guess 9th gear gives a cadence around 45rpm, its still slow at 35 btw.) The bike feels like it has significant drivetrain friction when pushing it downhill at speeds above assist. The controller will read ~25W and you need to pedal pretty hard to continue to accelerate downhill. (This sensation could just be the loss of assist, hard to tell.) I just know that on my road bike when pedalling downhill the pedal input gives much greater response. Enough difference that I am fairly sure on any longer descent, most road bikes would outpace a CCS or RCS.
I have not looked at the spacing of the gears on the rear cassette, but it feels like a big jump from 8th to 9th. Because 9th has so little utility on these bikes, when it comes time to change my cassette from wear, I will look to a cassette with a 12T or 13T top gear.

Agree, I've gotten used to it but I think the cassette is a mistake. You could shave off the first and last cogs and you'd never notice. A 12/13 - 25-28 would be ideal (havent tried yet, so I can't pin it down). With the current cassette, I'm often wishing I could be in between existing cogs.

I actually need 1st gear on occasion. One of the routes I take on my ride into work has a hill that peaks at 16% grade. Its not particularly long, maybe 500 yards, but it still slows the CCS down to about 11-12 mph even in S mode. Still beats my road bike where I was going about 5-6 mph along the same area.
i would like better spacing though on the cassette. I am probably a little spoiled from the years of road biking. I could always find a gear with a comfortable cadence with 30 speeds to choose from.

I use the 1st gear on a certain route I take sometimes. It goes through a playground. When the ground is soggy, that first gear gives me the torque I need. I put it in Eco and do as much of the work as it will let me, the motor doesn't like that kind of load very well.
Also, there are a couple of stretches of road where I shift into 9th. Smooth surface, slight downhill. I can hit 28 mph or so in level 2. Cadence is around 60. I think I'm more comfortable at lower cadences than @Chris Hammond - it only feels like 45 rpm to you, dude.
Seriously, though, in 3 or S it would be a slower cadence.

Well I learned this morning with a full battery that 9th gear is useful, gotta love going 35+ on a bike.I use the 1st gear on a certain route I take sometimes. It goes through a playground.
