getting a puppy | crate traning

hello!

next week i'm getting a 10 week old lagotto puppy. I'm asking for advice mainly regarding crate training and housebreaking, since that was something I never (fully) trained with my previous dog (poodle) and i don't want to make that mistake again.

I'm a college student that travels, I'll be away from home 4-5 days a week for 3 to 5 hours. I'll try to minimize any other outings while the puppy settles so I can train as much as possible.

I'm looking into crate training because quite frankly, i'd like to not have my house destroyed while away from home, i debated just leaving the puppy on my fenced porch during my outings, and i might do that sometimes, but i'll try to crate train because i've heard about the positives and how it accelerates potty training.

my main questions are:

how do I go about crate training? in a sense that is it okay to from the get-to start leaving the puppy in a crate for 4 hours daily during outings?

when can i start expecting the puppy to be able to sleep through the night?

when can i expect the puppy to be okay with being a travel buddy? (I have a beach house and I occasionally stay at my boyfriends house, i'm curious how long it took for you guys to start trusting your dog enough to bring them to other houses and stay overnight without accidents, as in start giving freedom)

I've never crated a dog so this is new to me, thank you!
