Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX540 HS is significantly lighter (174g ) than the Panasonic FZ80D which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot SX540 HS nor Panasonic Lumix DC-FZ80D (Lumix DC-FZ82D / Lumix DC-FZ85D) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon SX540 HS and Panasonic FZ80D's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
