HSE on-board oscillator from X3 crystal (STM32 NUCLEO-H743ZI2)

Hi

I use STM32 NUCLEO-H743ZI2 development board for my project. 
I'm considering purchasing electronic components for the first time, and I would appreciate a recommendation for an X3 crystal that could be used in this situation.

Additionally,

  • I understand that I should leave SB44 and SB46 as they are,
  • Solder and connect SB3 and SB4 each,
  • Solder 5.6pF capacitors to C69 and C70 each, and
  • Remove the 0-ohm resistor at SB45, correct?

My board is currently in this state,

and I plan to solder as described in the following diagram.

Thank you! However, can I just solder using the method I described? I'm a beginner and want to make sure.

Yes I confirm.

  • Leave SB44 and SB46 as they are,
  • Solder and connect SB3 and SB4 each,
  • Solder 5.6pF capacitors to C69 and C70 each, and
  • Remove the 0-ohm resistor at SB45

This is based on the schematics:
