The front suspension on E34's is kinda different than a lot of other cars in that there are a lot individual suspension elements that come together at the hubs to support the weight of the car. I would be a little afraid to support that weight using only one of those elements.
Of course, using the factory jack at the frame rail jack point is the best method for jacking the car. However, I've also used a floor jack like you when doing brake service. If you'll look under the car and inboard of the factory jacking points, you'll find a large square rail. That's where I jack my car from. I usually only do one side at a time, so I jack it up only high enough to put a jack stand at the end of that rail where it meets the front suspension mounts. I typically keep a little tension on the jack to help support things. I think it's important to have two different supports there in case something happens to one of them. Just thinking about getting pinned under a rotor is enough to keep me over cautious!
In reference to your car, if you haven't noticed anything different in the handling or tracking, you're probably okay. I just wouldn't recommend doing it again.
