When we built our house 25 years ago, we used an online program similar to https://www.suncalc.org/#/40.1789,-3.5156,3/2022.07.24/09:59/1/3 The app is immensely more powerful today! Also, install a compass app on your phone (Compass for android is really good). Gives you specific coordinates, altitude, etc.
We live in Udon. We ended up with the long end of our rectangular house oriented about 85/275. Single story. White steel roof. Large 3m overhang on southern side and eastern side. Carport on western side.
Here's a few things we've learned over the years. The sun never hits our southern facing wall. Our northern wall gets maybe an hour of sun at the peak of summer.....no impact. We underestimated the impact of the morning sun......should have built a bigger overhang there, but made up the difference with fast growing wall of green palms. Our western facing carport prevents the sun from ever hitting our western facing windows, but we had to plant a wall of palms to keep the sun from baking our truck. The palms solved both the eastern/western problem. Our northern facing windows/walls are never affected by the sun.
We have a 7' wide porch along the entire length of the southern side and the width of the eastern side.
In short, I'd say do whatever you possibly can to prevent the sun from hitting your exterior walls.....whether it's orientation, overhangs, trees, whatever. If the sun hits your walls, you pay the price for the impact long after the sun has passed on as the walls retain the heat.
I'll be surprised if you can find a ready built that meets your needs, but good luck in your search.
