Favorite FTP client for iOS where you can also edit files? So could maybe also be a text editor with FTP capabilities...
Found what I need: Code Editor. Will sync settings with Transmit on OSx as well. Bit expensive, but at least not subscription-based! 😁

Thanks @notenoughchairs
So apparently Panic's Code Editor is what was formerly known as Coda. :)
So thank you to all who suggested this even though it confused me ;)
Because the Coda app I found was something else.
