USB 2 and ASI462MC

I expect a considerable reduction in frame rate over USB2. Do not use a hub. That can make things considerably worse.

Or a Pegasus power box.  Just another option that would allow you to use your PC still, while options to power other things on the mount.  It is a powered USB3 hub, that unless you are simultaneosly running other cameras, equipment, would do the trick.   Just another option.

Planetary capture, assuming sufficient RAM for buffering and/or fast storage, is ideally bus limited (esp lunar, with bigger ROI).

USB3 on ASI cameras is 4800Mbps (no 10Gbps yet). Dropping to USB2 slashes that 480Mbps - a 10x reduction. On top of that, the protocol for USB3 is more efficient, allowing for more of that bandwidth to be used for actual data instead of command and control overhead. So realistically I think you may be looking at a factor of about 12 in performance drop.

Forget about wireless (for the data transfer), it doesn't come even close, especially in real world circumstances. It's really worth the effort to get a working USB3 connection to the camera. Ideally a direct connection - hubs can be bad news if there's "chatty" devices (like USB-to-serial links - very common in astro) on the hub. A small form factor PC (Intel NUC or similar) mounted on your telescope pier or under your tripod which you can admin remotely (RDP/Teamviewer/NoMachine) is great for this.

I have no issue with the right hubs.

I think the problem people have with hubs is that they don't power it and use cheaper hubs from consumer electronics stores.
I use to have troubles with those hubs (multiple brands)
Now, I use (so called 'industrial') hubs from StarTech, Gearmo or the Kendrick hub. 
Ensure you give those hubs enough power (ie. cable should be thick and short enough so no voltage drop at the hub)
You also should use quality cables such as those from L-com. Cables such as those flat USB3 cables supplied with ZWO cameras etc. should be avoided.
Go for cables up to 3 metres for faster speeds and not the 5 metre USB3 cables.
Also, don't exceed the max number of hubs in a run.
Keep in mind an "active" cable is just two normal cables with a hub to join them. That hub also needs to be able to draw power from it's source and laptops often can't supply enough current. Also, those 'active' cables often err for multiples of 5 metre sections which doesn't help the faster USB3 speeds
Also keep in mind a cheaper laptop might have an internal hub to give extra ports.

USBTREEVIEW (windows) is your friend for checking out your USB topology
I put together some info on serial links (ie. S in USB is serial) last year at the start of COVID lockdown
