Modern wheels are 700c, which is slightly smaller diameter than the 27" original wheel on your varsity, so you will need to buy a 700c tire. The hub axle spacing is 120mm on most SSFG type wheels like the one I linked, which is the same as old 10-speed frames like your Varsity, so that wheel will fit fine. You still need to buy a fixed cog and lockring separately. If you keep the original cranks, then the best chainline will be with the chain positioned on the inside (small) chainring.
