Avoid all of them! Nothing with DM. Use Tylenol for fever and aches and pain. Plain Robitussin for cough. Fluids, menthol rub, and cinnamon. Any cold meds can cause the mucus to thicken and cause issues with asthma or breathing issues. I have found this out over time.
When my kids were small a pediatrician told me to never give them cough syrup. Makes the cough worse and prolongs recovery. I was skeptical but I tried it. My kids got better faster with no lingering cough.
I started doing the same for me. I still get bronchitis but not as often. This is what works for me and could be different for everyone.

Good AI answer. I use Delsym for coughs and for nasal congestion Arm & Hammer NIGHTTIME Simply Saline Nasal Spray with Eucalyptus and a commercial essential oil blend called Respire.

Always read the labels with cold medicine. Many of them raise the BP. If you're not sure check at the pharmacy. Though googling it works too.
