As a parent of an adult child leaving home and an 8 year old, I can confidently say "don't worry about it".
First part: teaching the use of digital tools
The instruments your child is likely to be exposed to initially are designed so that a child whose family is completely illiterate can learn to operate them in about 30 minutes without any instruction. They will learn to use the tools very naturally.
By the time you child is ready for formal training, the devices will likely have changed enough that anything you plan to teach now would be obsolete.
My son only recently started any formal training (programming Java with CodaKid - he wanted to make minecraft mods), and that was because he wanted to do something specific that of interest to him, that was outside of my direct experience.
Second part: teaching to not be dependent on digital tools
The reality is, for good or for ill, our society is dependent on digital tools. Even school textbooks are now being distributed electronically rather than in paper form at many schools. It is cheaper for schools to supply electronic devices to read the text books than it is to buy the paper books. By the time your child is in school it is possible that paper textbooks may be a thing of the past.
In my state, every child is given a school administered g-suite account when they enter public school. By 5th grade they are expected to hand in some assignments electronically. By 10th grade almost all assignments are handed in electronically.
My family's solution is not for everyone - my son is home schooled, so he is almost always under direct parental supervision. The kids and families he associates mostly share similar principals.
My own son has just about every digital tool he can, not because we set out to load him up digitally, but because he's inherited his adult sister's hand me downs. Once the novelty wore off, he uses them as appropriate with little need for deliberate parental input. He has his own youtube channel that we post to from time to time as he makes videos, and with it the Google G-suite that he and I use to converse when I am working. So far he has had no need for other social media.
He is active in Trail life USA (outdoors program similar to scouting), holds his own playing tabletop games (various card games, D&D, etc) with older kids and teens at the local gaming shop, plays with legos, and is generally doing things other kids his age do.
Personal observation and frustration
One of my frustrations working with a teenaged webcast crew is that some kids devices are locked down to where they are useless (they can't even dial into the tech crew conference call or run the intercom software) and the training courses we subscribe to offer their "face to face" time with the instructors on Facebook, so families with "no social media" policies lock their kids out of the core training materials.
