Hi, Nightmare99. I'm playing Monarch too, and winning most of my games lately, and with different leaders. I just wanted to say there's no unique & perfect research path, it heavily depends on the leader/civ and the available resources.
First thing I always consider is: do I have a good early Unique Unit? If yes, I'll try to beeline for it to take a couple of scalps before it obsoletes. Latest example is a Hatshepsut with her wonderful War Chariots. I built two cities, took down Hannibal (he had three) with War Chariots only (he had one Spearman, the rest Archers), got Montezuma to three lousy cities with War Chariots + a few Axemen + Swordsmen, and also attacked Elizabeth with Axemen + Swords + Catapults + rest of War Chariots. I built only Stonehenge for the Great Prophet points (as I didn't need the culture boost being Creative) but wanted settled Prophets to fuel my war.
Second thing: who are my neighbors? In my Hannibal game IIRC I had Montezuma and Alexander. No way to live peacefully with those. On the other hand, in another game in which I decided to go for religions and cultural I had a 5 civs continent and never went to war just because I stayed away from actually adopting any religion, and let the AIs fight between themselves.
Third: I limit myself to only useful wonders. The temptation is very big to go for everything in sight, but even if you're Industrious AND have Stone and Marble there is such thing as too many wonders. The Oracle is a good early wonder, but if you have stone you might consider Stonehenge or the Great Wall. It also depends on the amount of forest's you can cut to speed up those wonders. Keep in mind that going for the Oracle AFTER the worker techs means you don't get the special benefit of founding a religion with the intermediary tech (Polytheism or Meditation), so you're researching three techs for one wonder. You might as well go for Alphabet directly by then.
Now about what I get from the Oracle: if I do bother with it, a lot of times I do it so that I can get Metal Casting. I do this especially if I'm Industrious, so that I get the cheap forges in fast. Alphabet is pretty cheap compared to this, or even to Code of Laws. If Confucianism isn't founded I consider Code of Laws a very viable option.
For more info you might want to look into Sisiutil's All Leaders Challenges. He's moved to Monarch lately and his stated goal is to use the leader's traits the best he can. They're a great read and a good learning tool.
