That's alot of sand. A nano can be as small as 10 gallons or less (depending on what your personal definition of a pico is). 3 inches of sand can take up alot of room. It's totally tank dependant but many people in the nano community prefer running even more shallow sand beds. As little as 1 inch for most of them. With such a small foot print, a deeper sand beds will just add to problems and you just don't get enough benefit out of it to justify having it. Many people will even go bare bottom for ease of cleaning. But if you want sand it's going to be purely based on aesthetics and any livestock. 1-2 inches is usually good enough for some typically burrowing snails etc. But OP is right in that, if you expect rock slides... then u better have some more protection. If not, then I'd advise a shallow sand bed.
One extra thing to add, an ATO is important in a nano. The smaller your tank gets, the faster the evap will have an affect on it. Unless your really religious on topping off using RO/DI water, it's a good idea to invest in an ATO to make your life easier.
