Here are the official boards under active production with "native USB" capabilities:
- Arduino Leonardo
- Arduino Micro
- All MKR Boards
- Nano 33 IoT
- Arduino Zero
- Arduino Due
- Nano 33 BLE
- Arduino Portenta H7
As mentioned already, there are quite a few other 3rd party board options as well. The only ones of those I have experience with are the Teensy boards and the SparkFun Pro Micro, which are very nice.
