If I were doing brake work I would do each wheel at a time.

On the front I would use the car jack to raise the car and place the jackstand under the rubber pad on the valance panel. Would keep both devices in place while I did the work then move to another corner.

In the rear I would use the car jack to raise the car, the jackstand under the pad and the floor jack under the rear axle - using a wood block I would not let the floor jack raise the rear axle, but just let the jack touch the axle.

Safer to put each end up on the two jack stands, however, lifting the rear end by the axle is not good, plenty of people do it cause they have to, but for brake work you don't.

And you cannot get under the car using the method I describe. Ramps are the only method for using a creeper under the car.

If I were working on a car where I needed to put one or both ends of the car up on jacks, I would use jacks like these on the inner jack points not the rubber pads if the car has them and keep a large powerful floor jack in use taking half the weight on front crossmember or rear axle.
For inner jack points you need either rubber or wood as protection to prevent underbody scraping of undercoat.

Also as a precaution I like to use a rubber mallet and a spare tire as a wedge on the down tire to prevent any chance of roll.

This is what I do, just me opinion
