Seems like they had a 2019 MBP which would be suitable.
Anything you get will be better than the 2013 she's giving back. Only issue with getting a newer model is having to buy adaptors/cables for usb-c, which will make it a bit of a faff to get everything connected to begin with. If you can get one of the M1 Air's I'd go for it.
This forumbod has sold a couple of refurbs on here.
