While Azure is right about it not mattering if you do all the sidequests, Fort Dawguard has a decent amount of loot, alchemical ingredients & food in it which will respawn over time like at other locations.

Also a side note, if you don't do ALL the sidequests, cure yourself and try to enter Fort Dawguard, they will be hostile. Even if you aren't a Vampire(Lord) anymore you were their enemy and will continue to be their enemy.
