Above material is Hem-Fir. A group of Hemlock and Western White Firs. Selected for appearance, 80% FOHC. Treatment does not affect structural quality of material. Good luck with your project!
Good question. Construction Select is intended for applications where code approved treated lumber is called for, like deck joists or any structural member. Those products have more preservative and incising to ensure full penetration of the preservative. Outdoor Select products are intended as non structural appearance products, like the surface of the deck or railing, balusters, etc.
We do not stock in 5' & can't cut. This is something that their local store might be able to do.
They weight varies a lot based on how dry the wood is after being treated. Based on your strength, a 4x4x10 may be a bit difficult for some people, especially if it still has a lot of the liquid treatment product in the timber.
At the time I bought it, the price was $23.97 for the 10 foot 4x4.

Yes I just had mine cut in half. Home depot did not charge me , but always assume additional costs for additional wood cutting at all hardware stores.
Yes it is well treated for ground contact and weather conditions. Except where cut.
