So the hair, the rolling in stuff, knocking things down & needing a lot of exercise seem to be the worst of it.
Do not under estimate the hair. It is all year round and then twice a year they go into a major moult for weeks, usually over Xmas for us when I'd like the house locking nice, when regardless of how often you vacuum the hair will be back within an hour or so!!
First 18 months regardless of how many toys you buy they will chew and destroy everything, until teething is done. Ours destroyed through chewing (usually during the night) every bed we bought him, new boots, skirting boards, 6" off a carpet, a sofa seat cushion, kitchen cabinet door and more.
He is 6 now and had cost us/the insurance over £6k in vet bills for various minor issues and one knee op.
They are constantly hungry and you need to say no to those beautiful pleading eyes several times a day. Labs need to stay very lean to prevent health issues. If you find the right food (usually expensive) farts can be kept at bay.
Everything for a lab/costs more. Flea/worming tablets, medication, health plan etc go by weight and they are heavy dogs.
After all that, there is a reason they are still so popular, they are simply the best dogs in the world. Not sure I'd want to go through puppy chewing stage again, might look into rescue next time.
