I found that I purchased these in August of 2021 by the ebay vendor listed as " kidd 2127 "
They have changed their name, and are now listed as " MYUNG YOUN ELECTRONICS (390) ". The link is below.

Thanks. They look to be static phase converters, but I’ll start a new thread.

I'm guessing I'll need to get some cable to hook up the inverter & motor, when it arrives, as I'm assuming it'll be 4 or 5 core cable required? I've never used 3 phase gear before, so I've no clue.

I would use 4 core SY screened cable. You can get proper glands for it, but I use normal 20mm ones and twiddle the screen wire into an earth sleeve and wago.

Would this cable be okay for a ¾hp motor?

What glands will I need, if I'm using the proper glands for it? I want to keep things as simple as possible, with me being a 3phase virgin.

there is no need to terminate the earth screen either end

This is from the Allen Bradley manual for the VFDs I use. It shows 3 phases and ground shielded with both the ground wire and shield connected both ends, I used 4 core SY with CXT glands on my lathe with an electronic leadscrew and followed the diagram because of the electronics and encoders. I use the unshielded 4 core rubber flex that came attached to my bench grinder without any issues.

What’s the reasoning behind leaving it floating?

there is no reason for it to be conected unless its being used as a screen ,if it passes through an insulated gland and the brading at the ends is insulated no earthing is required
