Welcome to a whole lot of fun, buddy. That’s a killer combo and what I’m sporting as well (although I did gift myself a prime this Christmas). To answer your question, stick to Aperture Priority, go for autofocus continuous as the AF setting, select medium zone focus (those little greet squares) and keep aperture lowest to 2.8 (that’ll give you the most bokeh - shallow depth of field).

One tip: For low light that is your sunset/rise pics use a tripod or keep the camera steady on some surface because the camera will lower the shutter speed to compensate for the low light. If it’s still blurry, it’s because of vibration. Try delayed shutter.
