Chrono Trigger is still being sold actually, so probably not the best example. That said, I still have my original PS1 Chrono Trigger disc that I haven’t played on original hardware (or even my still-hooked-up PS3) for a while because I legally dumped it and play it with a much higher emulated disc read speed. As much as Nintendo has made explicit statements to the contrary, it is legal in most countries to back up your own games and do with them what you will.
It’ll be compatible with 5 Gbps devices, but if you’re intentionally looking to restrict even 10 Gbps devices down to 5 Gbps for some reason, you might be able to find something in your BIOS that lets you do that, or you can get a USB 3.0 extension cable that’ll limit your speeds to 5 Gbps.
