I recently started using Fedora with btrfs, which I think was the default on install. So far all I've noticed is that backups and restores are really fast and easy.

Are there any important things to be aware of, like speed, drive lifespan or energy efficiency?

One thing not mentioned, BTRFS supports transparent compression which hypothetically can increase the longevity of SSD media by reducing the amount of writes to the drive.

I say hypothetically because further information on use case (potential write amplification from CoW) could nullify those gains — but frankly, SSD write longevity has improved so much that it is not a huge issue at this point.
