I had our rim joists sprayed when we finished the basement along with all our 1/2 walls (back 1/2 of the house has daylight windows in the basement) and it made a MARKED improvement in heat loss/air infiltration. I also did the concrete walls in the finished section with no-ill effects. What would/could be the downside? This is closed cell foam and has been inplace for 8yrs or so with no issues

I was watching "Cabin Masters" the other day. They remodel wilderness cabins. They like spray foam insulation. They claim it keeps the "small critters" out. An unsung advantage.

It really doesn't. I have a gun that I didn't treat right that doesn't work any more. Keeping it around because the idea I can't get replacement parts for it is really annoying.
You don't have to clean a gun, just leave a can of insulation on there. It doesn't matter if the can is empty, it just needs to have enough propellant to keep air (water really) out of the gun.
You don't have to believe me, just google and read up. I think everyone ruins their first gun. The truth is, my first gun is dead because I thought I had to take the insulation off and clean it for storage. The solvent doesn't clean it well enough and it gets gummed up. Wasted so much time on that gun, don't even want to think about it.
There is a solvent that will dissolve the dried foam. MEK maybe? Didn't think it was worth it.

Any future modifications would be more difficult. Fishing wire, plumbing, adding walls etc. Basements don't require as much insulation (R-13/15) and you shouldn't need to worry about drafts. -glass is just easier to deal with and a lot cheaper. If I were insulating between roof joists, I consider foam but I can see it still causing issues if I need to work on the decking. But, closed cell is the right way to go in a basement to stop moisture issues if you're dead set on spraying. Usually, a plastic barrier is used for fiberglass. I'm always remodeling and foam would screw me up big-time.

I decided to go with fiberglass batts. I'm glad I asked, I really was thinking that most would endorse spray foam.
Tomorrow I tear out the old wall and frame the new one.
Using 2 x 6 with 1/2" ply, 1/2 " foam, then T-111 on the outside and Fiberglas with a 6 mil vapor barrier.
Wish me luck .

you could still use some cans of spray foam to seal around perimeters of openings and also top and bottom plate and at both ends of the wall to help stop any leakage.

I did use cans of foam around the penetrations. Tried to post pics of progress last week but site was having issues
This is how far I got on my week off, with the snow wind and rain I didn't get finished
Still need to hang the storm door and insulate and drywall one side
