Aerodactyl/M-Aerodactyle are the fastest who can learn Stealth Rock, Roar/Whirlwind, and Roost, coupled with decent defenses
Alternatives are Arceus, Archeops, and Lycanroc.
Skarmory isn't fast but also fits this criteria.
Just a word of warning though, no amount of speed will make Roar or Whirlwind go first, as it has a -6 priority.
