Those will do the job just fine for your first build. I would suggest trying to find a PCB with more basic key placements as it's gonna be tough to use one with so many layout possibilities for your first build. Although I do get that may be the only 60% PCB available to you right now. If that is the case & you have to go with that PCB, use the keycaps to ensure you get the switches in the proper placment for the layout you want.
