That’s not how computers work, but sure bro.

Sure, you might.

But Baulder’s Gate 3 for example, which claims to require an SSD in it’s system requirements runs just fine on a HDD.

It’s just the developer making sure you get optimal performance.

It’s not a hard requirement.

I’d choose which ever one is not PostgreSQL.

No USB cable has “gigabit speed”. It probably has 480 Mbps (USB 2.0 standard).

Maybe he meant a 5 Gbps Gen1 cable. That would be “gigabit speed” but still rather slow by today’s standards and won’t support DP. They are pretty cheap these days, so wouldn’t be suprising to see left over stocks being sold as charging cables.

That sounds like a dedicated charging cable. So yeah, they will (if at all) only transfer data slowly and not support any extras features like displayport.

You won’t find these symbols on most devices though (certainly not on any macbook as the picture suggests).
