The eelctronics repair was more of a background skill idea - lonely intelligent kid who likes tinkering with electronics.
Then I had to chooce a specialty - well if I'd already chosen computer operation(massivley common skill in our era) and I'd think for a kiddo who likes speding time at the computer it might be a suitable specialisation.

But my first though would be something like no specialisation electronics (hobby electronics?) etc. You have probably encountered such hobby-ists I know I have.
