Jail is for both pre-trial and for inmates serving sentences of 1 year or less (give or take; that's decided at the county level so it's just a rough rule of thumb; for some it's 18 months). Also, the vast majority of "executives" never see the inside of a cell, even pre-trial. They might be in a holding pen for a few hours, but they always make bail and if the judge/prosecution is particularly concerned, the suspect gets additional conditions such as some kind of monitoring/curfew. A great example is Paul Manafort.
