>Favorite sealer that gives a little gloss
There is no good or recommended sealer for stone that add to the final lustre/reflectivity of the material. Why? Because stone will rot and weaken if moisture can't escape, and a lustre alerting sealer always caps the pores of the stone. There are two specific products I recommend. For natural stone where you just want it sealed, Lithofin PSI. For stone you need "enhanced" to make it look dark/wet because it's honed, Tenex Ager or Tenex Ager Tiger. I never use anything else unless outdoors but that's another topic.

>Why unsanded grout
Many reasons to not go sanded and an excellent question. First of all, marble joints are typically much smaller than normal tiles, sanded grout cant get in there deep enough to really do it's job well assuming those tight joints. "As long as you are careful" doesn't matter, natural stone required repair in the future and sanded grout interferes with this process by scratching the floor during grinding and polishing stages. It's very frustrating to be at your final grind and picking up pieces of sand that is leaving banana shapes scratches everywhere. Never ever use sanded. You can use ultraflex super or wtv (orange bag by mapei) it doesn't scratch for some reason.

>Favorite product for cracks
Gold brand clear polyester resin epoxy. Much harder to work with than typical stone resins but does an amazing job and lasts a lot longer.

>Scuffing
40-60-80?!?!! Noooo, way too aggressive. 50 and under is for shaping or lippage removal, light wear is 400 grit. 800-3000grits are there to feather previous grinds and are never really used on their own, only to bring back smoothness and prep for polishing. Typically a scuff can be removed with just polishing using a hybrid chemical/mechanical compound. This means the polishing powder has some acidity to bite into the stone but not so much it erodes it. This will often hide a scuff if you know how to use the product properly (it's not easy).
