Welcome!

An electric trimmer will be your friend if your goal is to sport a short/med length beard. I would use guards ranging from .5 to 1.25 inches. A 1 inch guard might be a good length for you now. It will even your beard length out. Then every 2 weeks repeat. I did this last summer. A boar brush is helpful for taming and shaping beards. I would recommend a soft boar brush. Nothing wring with clipping strays with scissors. Very nice beard by the way. You will have a nice professional look with a little maintenance.

Best,

Erik
