In a normal well, 30 feet or deeper, the spruce would not be a problem with roots getting into it.
However, if you need any well work done, you'll want to give the truck and workers room to work around the well. If you ever need to replace the pipe from the well to the house, you will not want spruce roots in the way.
As far as geothermal, the roots won't be a problem with your system. However, if you get a leak that requires digging up any of the hundreds of feet of plastic, you won't want an extra tree there. The mature Cherry tree was there first, so the pipes aren't unter it. With a sruce, you can't be sure.
