I have a new home that needs a railing system on the back porch. The porch posts vary in distance 7’, 11’, and 12’ apart, based on the asymmetric design of the home. I don’t want to obstruct the view more than needed, so I’m wondering what my options are for spanning the distance without adding additional posts. Appreciate any thoughts.

Check out metal railing systems. More strength in smaller profile. pick a dark color and it will fade into the background.
for a wood railing, you can go to 6 ft, but 4 ft is a better idea. the longer the span, the thicker you will need to make the railing.
Thank you.
Check with the local code officials. The 7' is probably allright for wood or composite but not the 11' or 12". Rail posts would need to be anchored into the floor framing, again check the codes.
Cable railings are illegal in many jurisdictions. Children climb when not attended. Even the new range, stove, oven or hob, whatever you call it in your country, which was delivered just last week has an anti-tip floor bracket. Look up the stats on injuries and deaths of children due to climbing on furniture--bookcases and dressers. I broke my arm climbing out of a playpen at 3 years of age.
As suggested, look into black aluminum railings. (I used such a system.) Be aware that due to galvanic corrosion, you must electrically isolate aluminum from pressure treated lumber. You might have a cedar deck and think that you're OK, but..... even the steel bolts which anchor into P.T. sub-structure must be isolated from the aluminum posts with plastic washers.
