Congratulations on your new home - how exciting! I would not paint the walls grey/blue/green due to the orange/yellow wood. Those colors would look nice in your home but may feel a little old-fashioned to you. In my opinion, grey has been overdone and it's time for something fresher. I would paint both the walls and the wood trim the same soft white to give it a more modern feel. The trim is not very substantial so just paint it out altogether. Bring in color with your furniture or art. When you eventually replace the flooring you can think about changing the trim too. Look at Benjamin Moore OC-117 Simply White, or perhaps OC-118 Snowfall White or OC-149 Decorator's White.

Also, I used a product called Samplize when I was testing paint colors that was amazing. And more efficient than buying all the little sample size paints to test a swatch. If you sign up for email, you get a $5 off coupon. And you can move the samples to different walls and compare at different times of day. I found this very helpful. https://samplize.com/

@Jan Moyer and @houssaon I agree. I had been looking at these dilemmas because my front door is not at the front, ha, ha. The bottom line from all the recommendations has been to emphasize the front door, not the garage doors. So I would say: paint the trim AND garage doors the same as the house. For the same reason the house numbers should be located by the front door, not over the garage door (answering your second post). Good luck with your project!

@er612 Thank you SO much that was incredibly kind of you to do those mock-ups. SO helpful. Could I trouble you to do two more with this photo? (Roofing is done so no more ugly tarp hanging over and we put up lights.) If so, could you do the first one (white with pale blue door) but could you add black trim around the windows and roof line? And the light grey one (as is)? Thanks again!
