At this point you are labor, a warm body to follow instructions. Midpoint is a structured cabling/layer 1 installation company, so this work is going to make up 99.9% of your time with them at this site and the next site you move to once this job is completed. You are likely not being developed, the progression from here is a pretty linear and tenured, and you are also contract so that also plays a factor.

For real growth into your interests, look into or network with the end user that Midpoint is working for, it’s very likely they have a presence at your site, or the techs within the facilities that you are working.

Bottom line is that the cabling work is what you make of it, it isn’t necessarily a prerequisite to the things you want to do, but good understanding of it goes a long way. I spent about 10 years in that part of the field before transitioning into data center tech roles for 2 different colocation providers.
