hi, K. I feel your pain about just moving to an area and not knowing what to expect!
I'm not a rose expert, but maybe just wait this year and see what it looks like when it blooms? That could give you a better idea about where you'd like to trim back for next year. There were 2 rose bushes in my yard when I moved here in 2020. So far, I've let them be. As it turns out, I've been pretty busy just creating a new garden here and the existing roses have become less of a priority for me.
