The house is full of belongings and needs work. Where do I even start?

Separate the two jobs first, since clearing out belongings and addressing needed repairs usually require different people and different timelines, and trying to do both at once tends to stall a listing. A junk removal or estate sale company can typically clear a full house within days once you decide what to keep, after which an inspector or contractor can give you a real number on what repairs actually cost versus selling as-is. Deciding upfront whether to invest in repairs or sell as-is shapes every step after that. Joel Boss can recommend cleanout and repair contractors he trusts for exactly this situation.
