Blade 15 (Late 2021) SSD Slot

I have a new Late 2021 Blade 15 Advanced on the way and I'm considering making use of that freed up M.2 PCIe slot to expand the storage as a means of future-proofing space and helping to free things up for not only my gaming but video editing. The only thing is I'm having a hard time finding what form factor to go with. Link below to an SSD I'm eyeballing but of course open to ideas and suggestions. I know it has to be single-sided or it won't fit otherwise, but past that I usually know just enough to make me dangerous with my tech, so any help is appreciated.
