Welcome to philosophy! Learning to see both sides of every coin and to understand the arguments pro and con every position is a vital philosophical skill. There are few things as dangerous as people who are sure they are right. Usually, they are the most ignorant and the most stupid.
The fact is, intelligent and well-educated people disagree about a great many things. This is a natural state of affairs, and is healthy. Our knowledge grows when we advance ideas and then criticise them. Though, as you have observed, being good at seeing both sides can make it harder to make decisions. In my view, that is a price worth paying.
Some considerations that might help:
For a given problem, make a list of the arguments pro and con, and work through them in turn. Look for any clear errors or oversights. Darwin made a list on paper of the advantages and disadvantages of getting married before proposing. That's pretty cold-blooded, but the idea is right.
Try to think of as many options as possible, including unconventional, out-of-the-box types. Rank them by how plausible they are and how desirable or otherwise the outcomes might be.
Try to think of different ways of formulating a problem. Often, finding a good formulation is the hardest part of solving it.
Don't be afraid to challenge orthodox positions. All orthodox theories, even in science, were once considered heretical. (I believe Feynman said something along these lines, though I couldn't find the exact quote.)
Ask others for advice. It is unlikely you are encountering a problem that nobody has ever met before. Communicate and keep communicating. Sometimes just the act of expressing a problem clearly to someone else is sufficient to clarify it for yourself.
Try to think first and foremost in terms of concrete examples, rather than jumping straight to the general case.
Actively seek out the best and smartest thinkers on a given subject and try to understand what they are saying. 'Best' does not mean those with the most views or followers. Truth is not a popularity contest.
Take care to avoid groupthink. Part of the curse of social media is that it constantly presents you with information that you already agree with. Based on the documents or posts or videos that you recently viewed, you will be offered more of the same. It causes silos of thinking in which you are never exposed to those who hold contrary views. You should be spending more time reading people you disagree with than people you agree with. It is important to know what the positions are that are contrary to your own and why others are defending them.
Never stop learning. No matter how much education you have had, you probably know a lot less than you think.
Don't be afraid to change your mind. Changing your mind involves admitting you were wrong, and people are naturally strongly reluctant to do so. But changing your mind just shows that you are open to being persuaded, and that's a good thing. Equally, don't fall into the trap that just because you used to believe something and don't any more that it must be wrong.
At the end of the day, there is no single decision process that resolves all questions. There is no guarantee you will always be able to find a correct, or even a satisfactory answer to a problem. There is nothing wrong with being undecided.
