Jacks don't necessarily have the punchdowns in pair order, they "fix" the order in the traces between the punchdown and the socket. This makes it easier for an installer to just go pair by pair.
u/DiscontentedMajority posted the datasheet, this punchdown order is correct for this jack for T568A. Always check the datasheet or instructions, or verify with a meter.
In your case the new AX1800/AX20 with USB does support sharing the HDD as a Windows drive or via FTP.
Your phones would probably need an app.
