If you get slow results at the router, then move to the modem.

If you get slow results via hardwired connection at the modem, it's the provider or their modem.
If all the hardwired connections are faster, it's the wireless issue with the router.

As someone who doesn't know much about this, I think it's worth contacting Spectrum customer support to make sure there are no service outages in your area.

If all else fails, is there another provider in your area?

That Orbi AC3000 set-up is plenty fast and unless there's something about it that's broken, not likely to be the root of your problem. You say you tested first at night, and then again in the morning. Is it possible that other Spectrum customers in the area are generating sufficient load to overload the local Spectrum infrastructure and cause you to be throttled down from 300 Mbps?

Also see if there is new firmware for your router. It might just need an update.

I tested last night and this morning and the download speeds are consistent over 350 mbps. However, the upload speeds are less than 1 mbps. Not sure what is going on with that.

Download/upload speeds for cable are typically extremely assymetric and I don't think I've ever seen more than about 10 Mbps at home. 1 Mbps does seem pretty low. Based on your previous post it may be a transient condition, though. Regardless, it's probably not a concern unless you're uploading large (like 100 MB large) files from home.
