Or set up SFTP on the Linux machine, and find whatever Windows crapware that's able to connect to it... Filezilla, maybe?

Windows has had OpenSSH's ssh/sftp/scp client binaries built in by default for ~7 years now. You can also do this in reverse by enabling OpenSSH Server on Windows (included feature but not installed or enabled on boot by default) and having the sftp client be the Linux box, which can be easier depending which you have more control of.

Or just... put in a usb thumb drive, move the 50gb on it and call it a day?

If you don't have a thumb drive handy you could probably transfer it to your phone and use that instead

I think many (most?) modern phones have that much storage
