Beware: most USB-to-SATA adapters do not work with HDDs, only SSDs
One USB A-to-C adapter I particularly like is a cable with adapters tied to each end, so you can use it for any combination of (A or C host) to (C or micro device).
FM transmitters you have to be slightly careful - they need to get power somehow; think about how that will happen.

If you want to be sure that a USB to SATA adapter will work with anything, get the style that has the power on a completely separate cable that plugs into the wall.

A lot of cars without Bluetooth have a USB-A port for charging or plugging in a USB drive with music on it, you can use that port to power the FM transmitter
