Definitely a lateral because if the membrane tears you will need to fix it!
These are actually quite tricky.
These often results in tear due to limited space to enter. Hard to make large enough windows.

This is definitely an open lateral window case (not crestal). You are better off doing the augmentation first then placing implant 6 months later.
I'm not a fan of LASK Kit. I prefer using round diamond and round carbide especially in tighter space like this. My favourite sinus instrument kit is from Surgical Smart. Their gold tipped instruments are sharper than any that I have used.
Making the window will be your most difficult part here. I would rate this lift as more advanced and if you are unsure, having a mentor over the shoulder would be a better learning experience for you. Having adjacent teeth on either side makes this case more challenging.
Also, please do vitality testing on adjacent teeth and make sure CBCT confirms that there is no radiolucency at the apex of 25 or 27.
