I want this Amelanchier to grow to the height of the wood Cabin and then spread to form a canopy. Any tips? Should I prune the bottom or use a stake and tie any branches that get too close to the cabin to train it? Am a complete novice if this is not clear already.

Some are wide spreading trees.
Others such as Amelanchier alnifolia Obelisk are fastigiate....they only grow tall and narrow.
At a later date, you can then remove lower branches, thereby raising the canopy, but I doubt it'll look right. It would have been better to have bought one of the more upright varieties as already suggested.
I wondered if it was an Amelanchier @GardenerSuze - the flowers didn't look quite right. The foliage usually appears at around the same time - I can't see any, but it may just be the photo.

Ideally I would like a wide canopy. Realise it could be a good few years away.
I've had multi stemmed and single trunk varieties in various gardens but I really don't think you can change a multi stem shrub easily to create a single trunk shape with a high canopy, unless you had a viable single trunk from the start.
You can do it the other way round though, by cutting back a single trunk, as they produce stems/branches from low down anyway. They really want to be multi stem shrubs rather than trees.
