Symmetry is overrated! Strive for balance and proper function.

This is what I would do. Buy 3 outdoor sconces. One on each end of garage doors and one by the man-door. The left one will dictate the distance from the trim, for the rest of them, but I might not center it ... I would have to see it to decide the best position.

Function is the first need and I agree maybe even one in between the garage doors

Any outdoor lighting should follow dark sky principles:

To avoid emphasizing any asymmetry, you could install dark-sky barn lights or other downward-facing lights above the garage doors and the entry door. Examples:

• Project Source Oakdale 1-Light 12.2-in H Matte Black Dark Sky Outdoor Wall Light
• True Fine Tuner 1-Light 13.6-in H Matte Black Motion Sensor Dark Sky Dusk to Dawn LED Outdoor Wall Light (use a shallow bulb that's tucked up within the fixture)

Use low-voltage path lights along the driveway and/or between the garage door and entry door. Examples:

• Harbor Breeze 90-Lumen 7-Watt Specialty Textured Bronze Low Voltage LED Outdoor Path Light (3000 K)
• VOLT Outdoor Lighting 300-Lumen 3-Watt Bronze Low Voltage Hardwired LED Outdoor Path Light (2700 K)

To avoid illumination when it isn't needed, control the lights with motion sensor(s). Example:

• Utilitech 240-Degree White Wire-in Replacement Motion Sensor and Light Sensor
