Is it possible to do the well paid job for a while and grind it out to save some money then switch to the lower paid one after a few years?

I mean my current job has really shitty pay despite my title sounding fancy, so if I could do my dream job and get the same pay, great.
I can't answer what is best for your situation. Personally as I have gotten older I value my free time far more than money. My job doesn't pay great, but it's still more than I use in a month. If my salary doubled tomorrow, it probably wouldn't change much for me, I don't have a very extravagant lifestyle. On the other hand, if my free time doubled tomorrow, it would change a lot. My working hours are also "funky" (It's a 24/7 business so sometimes I work graveyard) but you get used to that.
That's speaking personally though. Straight out of university when I still had significant debts to pay back? I would value the higher pay, at least on the short term, more.
You mention family though, so that is another thing to consider. Personally I am childfree and never really need to plan for savings for a family. While I currently support my partner due to some stuff, she normally works as well so I don't actually have dependents normally.
My nondream jobs also have shitty pay, so ¯\(ツ)/¯ i guess
