I ended up going with the Raspberry Pi debug probe:
    https://www.raspberrypi.com/documentation/microcontrollers/debug-probe.html
If I remember correctly, it’s a pl2303 inside. I mostly got this model for the connectors and laziness.

Jeff Geerling mentions some of the other options at https://www.jeffgeerling.com/blog/2023/testing-raspberry-pis-new-debug-probe

If I were doing it again, I’d probably get the Black Magic Probe which also supports JTAG https://www.adafruit.com/product/3839
