Hello! Transition words are extremely important when writing your essay because like you stated in the question it sort of helps it flow and sound smooth rather than choppy. Over time I have become very good at placing transition words in my essays. Here is a list below of some great transition words.
-With all being said
-In any event
-As a result (of this)
-As a final point
I hope this was helpful! I wish you the best of luck with your essay.
