These are lower profile, and easier to solder straight, but more expensive: https://www.    aliexpress.com/item/1005006248653180.html (9P PH3.5 Female Header). Socketing is a long term choice: you can reuse mcu for another build, or more   importantly replace it easily if it breaks.   |   2.01 | https://www.aliexpress.com/item/4001122376295.html |
