Some nice work^^^.

I would recommend simply cutting the rafters. Yes. Cut the bird mouths. It’s easy.

If you are framing a gable, it is easier for the roof cutting, but leaves a bit more work for the wall framing.

Easy math: width of building devided by 2 minus half the width of your ridge.i would use 1 1/2” stock. 2×8 would be my preference when using 2×6 rafters. If you tell me the actual dimensions I can figure the rafter length for you. Basically it is Asquared times Bsquared equals Csquared, (sorry… Don’t know how to represent exponent in text on my tablet) throw in a couple collar ties or ceiling joists to prevent sag in the future.

I would also say that 16” on center rafters is overkill unless a heavy snow load is anticipated.

You could opt for something more decorative. (Like the site built trusses shown in the previous commenters post. Sweet!) if this is the case, consider using some old fencing slats to mimic a tongue and groove roof deck exposed at the interior. Ply above it. A trick I did here: The second picture shows a small loft, which in this case, eliminated the need for collar ties or ceiling joists.

Well….. I don’t know how to rotate those photos but they came out oriented 90 degrees off. They are of a similar structure to what you describe, 10×10 playhouse with loft using an old wooden play set, some fencing, and some new materials.

Build your walls and brace them plumb level and square, then cut one rafter. Use it as a template. Get a helper to set the ridge or on something only ten feet wide, you could manage yourself. Anywho… I’m rambling, but if you would like me to figure the rafters for you, I’d be happy to help. If you have never cut a rafter, it is quite easy, you just need the mental picture, a speed square or framing square, a pencil, a saw, and a power source. The power source can be your own elbow grease. :-) good luck!
