Problems with から, て form and で (because)


Well, searching around the web I came across this post ([Difference between から
and で in context of
because](https://japanese.stackexchange.com/questions/74184/difference-
between-%E3%81%8B%E3%82%89-and-%E3%81%A7-in-context-of-because)) that had a
similar problem, but it did not resolve mine. I found these three sentences:

夏休みがありますから、夏が一番好きです。

通りにまよって、おくれました。

じゅうたいで、おくれました。

I kind of understand the difference between the last sentence and the other
two (there is a noun before で), but in the other two there is a verb and I am
not able to tell when to use から or the て form.
