Does the box include a cable and do I need anything else to connect to a USB-A port?

The package includes the 4TB portable SSD, a 24 cm high-performance USB-C to USB-C cable and a USB-C to USB-A adaptor, so no separate purchase is required for USB-A connectivity.

Is there more than one capacity option for this Crucial X6 SE model?

The product listed here is the 4000 gigabyte version; no other capacities are mentioned for this specific model.

What do the 800 MB/s read and write speeds mean when I plug the drive into my laptop?

The quoted 800 MB/s read and write figures are the maximum sequential transfer rates over the USB 3.2 Gen 2 interface; real-world speeds will vary with the host controller, file sizes and workload.
