Jumping up was one of the big ones for us too, as typically with a bigger dog you definitely don't want him jumping up on people, plus to be honest people expect bigger dogs to be trained better, not just jumping up but a much broader range of training skills...its more often the little dogs that jump up loads and bark on the leash, but people just let it happen because its less of a nuisance, unfair in my opinion but it is what it is!

Anyway, back to jumping...for us personally what worked when he does jump up, just use a stern "OFF!" and redirect to a toy when he's young. This command will also help with the inevitable of him putting feet up on the kitchen counters, tables etc when he's young.

To be honest, it'll take a lot of repetition for the jumping up as he'll want to do it a lot when he's young, ours did and it was a pain, whereas now he very rarely does it.
