For the socket, I used these (24 pin wide version) works okay, will have to cut off some plastic when I attach a battery though. They're a lot cheaper than anything else I could find.
For flashing the bootloader, you can also use a rapberrypi pico with picoprobe firmware. This command line will work on ubuntu. openocd -d2 -f interface/cmsis-dap.cfg -f target/nrf52.cfg -s tcl and then follow the guide in the wiki.
