From Ashes: I would say after Sur'kesh. You will want to get him as soon as possible to hear all his dialogue, but it makes the most sense to do it after Sur'kesh from a gameplay and story standpoint. You'll fight an Atlas or two and several Engineers on Eden Prime, presented as just another enemy, but Sur'kesh gives them both proper introductions. And the Crucible is mentioned by name in a conversation with Javik that takes place right after, and you only learn the name after Sur'kesh.
Leviathan: Anytime after Thessia, would recommend after Horizon.
Omega: I would say after Priority: The Citadel II. Omega's tricky because it's long and feels very self contained, so I wouldn't recommend doing it in the middle of Story Arc. Right after Citadel II makes sense because the Genophage Arc is over, the Quarian and Geth Arc hasn't started, and it makes sense to wanna stick it to Cerberus.
Citadel: I would honestly recommend doing it after you beat the game for your first time through. Where as the actual end of the game is the "end" of the story, Citadel feels like the "goodbye" to the series. It's a shift in tone that can clash with the main game, though it is possible to play it in the middle of a playthrough. It's split up into three parts, the mission, the exploration of the strip and all the character conversations with your squad, and the party. So if you really want to do it in the middle, I would say do the first part after Rannoch, but before Thessia, so you are not in the middle of an Arc, but still have Tali, if she's alive. Make sure you lock in your romance before though. Then do all the character talks as you see fit, and then make the party be the very last thing you do before the final mission. Again though, I would still say Citadel is best after you beat the game.
