I find it suspicious they look similar and both function to give explanations.
Is it just coincidence or is ので kind of like the て form/mid-sentence form of
のだ?

question
words particles no-da
Is ので the same as のだ?
ので has similar meaning to から in that they can both mean "because, given
that..."  

のだ, or のです are versions of んだ/んです that are more often used in writing and they
don't really mean "because", they just imply the speaker or writer is
explaining or emphasizing things. It's quite hard to explain, you can read up
on it here:

answer
Yes, ので is related to のだ. This の sort of means 'thing' or '(the) thing is' in
the sense of 'it is the case is that...'.

For this reason, the difference between さむい？ and さみいの？is that the first is a
simple question, whereas the latter implies that you have reason to think that
the other person is cold. Perhaps they are wearing a heavy jacket or they
asked to put the heater on. Hence the second question is more like "is it that
you are cold?".

んだ or のだ has a sense of explaining what the situation is. Hence you often here
people starting with something like _今思ったんだけど_ _so I was just thinking,..._
Another example might be _スーパーに行くんだったら_ _if you're going to the
supermarket...(and it seems like you are)_

ので is the て-form of this construction. It provides a sense of explanation,
which is why it is similar to から and means something 'since' or 'because it is
the case that'. This meaning is slightly different from から because in the
construction **AのでB** I feel that it implies that the listener is aware of the
circumstances or would agree with the statement A, for which B is a
consequence.
