I have simple wall installed on my computer to try and cut down the content data that is sent to MS, but I have noticed that apps I do not even use seems to want to connect, MS store comes up as trying to connect, mail and calendar even the photo app.
Why do these apps want to connect when they are not even in use?

MS policy. All people get all updates to everything. Users get no choice to review value of update (e.g. unneeded program, worse driver etc). MS decides when the update occurs, and not you. If you don't like it, you can't exactly pick some other version of Windows, as all of them are either telling you to update to Win 10, or are out of support very soon.

Steam is similar. You can't play a decent range of titles without Steam. You have to have 3rd party software installed on your system permanently. Most of the time you also have to have net connection to Steam servers to play.

Welcome to the world where software companies fought back against greedy kids who wouldn't pay for software.
There was a workaround if you have the home (I'm assuming it still works). You have to tell porkies to your computer and microsoft and use settings to record you have a metered connection to the internet. This will stop some automatic updates.
