SWD interface Connector Selection for MCU Bootload

Hi!
I have a custom STM32H753ZIT6 MCU based board for which I am using SWD in order to bootload/program the MCU. To interface the SWD to either the STLINK or other programming modules similar to it, does anyone have any recommendation on what connect to use. From my research I have seen TC2030 being used in few designs but that is fairly expensive connector to interface with STLINK. Do you have any recommendation on what connector I could incorporate in my designs. I had an idea to have 10 pin female header connector with similar pitch to what stlink has as I observed the pinouts for SWD are on one side of 20 pin connector, could be a *** idea, if you have some better alternative please recommend.

Use a standard shrouded header that mates with the cable on your programmer. Either 0.1" or 0.05" pitch depending on your programmer.

For STLINK-V3MINIE, use Samtec FTSH-107-01-F-DV-K or equivalent and use the standard pinout.
