Whenever I boot Ubuntu the display and keyboard brightness are reset to maximum.

Since I almost never need such high brightness settings, every boot includes an aftermath of excessive key pressing.

I would be thankful if anybody could guide me to a solution to automate my key presses or apply new brightness settings automatically upon every boot. Thank you for your consideration :)

I had a problem like this (the brightness was all the way down on startup) and this is how I solved it.

Your brightness settings are just a flat file with a single number in it. It is probably one of these files, but you might have to do some checking to make sure.

/sys/class/backlight/acpi_video0/brightness

/sys/class/backlight/intel_backlight/brightness

Try running this in the terminal (change file name as appropriate)

echo 3 > /sys/class/backlight/intel_backlight/brightness

What I did was create a cronjob using the special word @REBOOT to run this command whenever the computer started.
