Looking for unpopular opinions that changed my mind [v3]

Posting this here because the relevant subreddit has gotten too noisy lately. There is a lot of conflicting advice online and most of it is from 2019. Long-time lurker, first-time poster.

Looking for honest feedback, not validation. Quick context: I am relatively new to this and trying to find my footing. Been thinking about this for a while and curious what the community thinks.
