Size matters.......................................
But not a lot, perhaps you are having a crisis
I've been down the same route 35mm, stopped that 5 years ago , 120 - 645 only for commercial work, 5x4 my main format, 10x8 now my preferred but not always practical format.
I think what you are talking about is the different ways of working, and I've found it important to keep working in different ways.
Recently I've started shooting 35mm gain for personal work, anything larger is 5x4 or 10x8, and more recently (today) 6x17.
Even when you're an LF photographer it's fun to exlore with smaller formats and what better than 35mm
And going back to lets get small, I made a series of images from 5x4 negs and used my enlarger to reduce them, for a small book.
You have to balance what you are trying to say against what you perceive to be your audience.
